Vue Chart - argumentAxis

Configures the argument axis.

Type:

Object

DevExtreme HTML5 Charts Axis Axes

The argumentAxis object, which is described here, configures the argument axis individually. To specify common settings for all axes in a chart, use the commonAxisSettings object. Axis-specific settings override common settings.

aggregationGroupWidth

Specifies the length of aggregation intervals in pixels. May be ignored in favor of the aggregationInterval option.

Type:

Number

Default Value: undefined

For data aggregation, the argument axis is divided into intervals. Series points that fall within the same interval get aggregated together. The aggregationGroupWidth option defines the length of each interval in pixels.

See Also

aggregationInterval

Specifies the length of aggregation intervals in axis units. Applies only to axes of continuous and logarithmic types.

Type:

Number

|

Object

|

String

Default Value: undefined
Accepted Values: 'day' | 'hour' | 'millisecond' | 'minute' | 'month' | 'quarter' | 'second' | 'week' | 'year'

For data aggregation, the argument axis is divided into intervals. Series points that fall within the same interval get aggregated together. The aggregationInterval option defines the length of each interval.

If the axis displays numbers, assign a number to this option. For example, an aggregationInterval of 100 produces the following intervals: 0 to 100, 100 to 200, 200 to 300, etc. If the axis displays date-time values, set this option to one of the accepted string values. Alternatively, you can set it to an object that contains one of the fields described in this section.

jQuery
JavaScript
$(function() {
    $("#chartContainer").dxChart({
        // ...
        argumentAxis: {
            // Interval of one day
            aggregationInterval: "day",
            // Interval of five days
            aggregationInterval: { days: 5 }
        }
    });
});
Angular
HTML
TypeScript
<dx-chart ... >
    <dxo-argument-axis
        aggregationInterval="day"> <!-- Interval of one day -->
        <dxo-aggregation-interval
            [days]="5">            <!-- Interval of five days -->
        </dxo-aggregation-interval>
    </dxo-argument-axis>
</dx-chart>
import { DxChartModule } from "devextreme-angular";
// ...
export class AppComponent {
    // ...
}
@NgModule({
    imports: [
        // ...
        DxChartModule
    ],
    // ...
})

On a logarithmic axis, intervals are calculated based on powers. For example, if the logarithmBase is 10 and the aggregationInterval is 1, the following intervals are produced: 100 to 101, 101 to 102, 102 to 103, etc. If the aggregationInterval becomes 2, intervals become longer: 100 to 102, 102 to 104, 104 to 106, etc.

When using the widget as an ASP.NET MVC 5 Control or a DevExtreme-Based ASP.NET Core Control, you can specify this option using the VizTimeInterval enum. This enum accepts the same values, but they start with an upper-case letter, for example, "day" becomes Day.

allowDecimals

Specifies whether to allow decimal values on the axis. When false, the axis contains integer values only.

Type:

Boolean

Default Value: undefined

argumentType

Casts arguments to a specified data type.

Type:

String

Default Value: undefined
Accepted Values: 'datetime' | 'numeric' | 'string'

If your data source stores, for example, numbers as strings, specify the proper data type using the argumentType option.

Use the ChartDataType enum to specify this option when the widget is used as an ASP.NET MVC 5 Control or a DevExtreme-Based ASP.NET Core Control. This enum accepts the following values: Numeric, DateTime, and String.

See Also
  • valueAxis.valueType - casts values to a specified data type.
  • argumentAxis.type - specifies the axis type.
  • dataPrepareSettings.checkTypeForAllData - validates the type of each value coming from the data source.
  • dataPrepareSettings.convertToAxisDataType - allows you to disable the type cast in favour of the widget performance.

axisDivisionFactor

Specifies the minimum distance between two neighboring major ticks in pixels. Applies only to the axes of the "continuous" and "logarithmic" types.

Type:

Number

Default Value: 70

For axes displaying numbers, the distance between major ticks depends on two interconnected options: axisDivisionFactor and tickInterval. Consider that you have specified both these options. If the specified tick interval leads the pixel distance between two ticks to being less than the axisDivisionFactor value, this tick interval will be ignored.

Use the axisDivisionFactor option only if you need to set the distance between ticks not knowing the axis values. Otherwise, use the tickInterval option.

breaks[]

Declares a scale break collection. Applies only if the axis' type is "continuous" or "logarithmic".

Type:

Array<Object>

Default Value: undefined
Cannot be used in themes.

A scale break allows breaking off a part of the axis to improve the readability of a chart with high amplitude values.

DevExtreme HTML5 JavaScript Charts Scale Breaks

Each object in the breaks array configures a single scale break. Note that a scale break is visible only if its range exceeds the tick interval.

See Also

breakStyle

Configures the scale breaks' appearance.

Type:

Object

categories

Specifies the order of categories on an axis of the "discrete" type.

Type:

Array<Number | String | Date>

By default, arguments on a discrete axis keep the order of objects in the data source. For example, objects in the following data source are sorted by decreasing area value. The resulting arguments will be sorted the same way.

JavaScript
var continentsByArea = [
    { continent: 'Asia', area: 43820000 },
    { continent: 'Africa', area: 30370000 },
    { continent: 'North America', area: 24490000 },
    { continent: 'South America', area: 17840000 },
    { continent: 'Antarctica', area: 13720000 },
    { continent: 'Europe', area: 10180000 },
    { continent: 'Australia', area: 9008500 }
];

To sort the arguments, for example, alphabetically, you need to assign an array of properly sorted arguments to the categories option.

jQuery
JavaScript
$(function() {
    $("#chartContainer").dxChart({
        // ...
        argumentAxis: {
            categories: ['Africa', 'Antarctica', 'Asia', 'Australia',
                'Europe', 'North America', 'South America']
        }
    });
});
Angular
HTML
TypeScript
<dx-chart ... >
    <dxo-argument-axis
        [categories]="['Africa', 'Antarctica', 'Asia', 'Australia',
            'Europe', 'North America', 'South America']">
    </dxo-argument-axis>
</dx-chart>
import { DxChartModule } from "devextreme-angular";
// ...
export class AppComponent {
    // ...
}
@NgModule({
    imports: [
        // ...
        DxChartModule
    ],
    // ...
})
NOTE
Arguments missing from the categories array will be added to its end automatically.

color

Specifies the color of the axis line.

Type:

String

Default Value: '#767676'

This option supports the following colors:

constantLines[]

Declares a collection of constant lines belonging to the argument axis.

Type:

Array<Object>

Cannot be used in themes.

DevExtreme HTML5 Charts ConstantLines

Each object in the constantLines array configures a single constant line. Setting the value option is necessary for a constant line to be displayed.

See Also
  • argumentAxis.constantLineStyle - specifies the appearance of those constant lines that belong to the argument axis.
  • commonAxisSettings.constantLineStyle - specifies the appearance of all constant lines in the widget.

constantLineStyle

Specifies the appearance of those constant lines that belong to the argument axis.

Type:

  • commonAxisSettings.constantLineStyle - specifies the appearance of all constant lines in the widget.

discreteAxisDivisionMode

Specifies whether ticks and grid lines should cross axis labels or lie between them. Applies only to the axes of the "discrete" type.

Type:

String

Default Value: 'betweenLabels'
Accepted Values: 'betweenLabels' | 'crossLabels'

Use the DiscreteAxisDivisionMode enum to specify this option when the widget is used as an ASP.NET MVC 5 Control or a DevExtreme-Based ASP.NET Core Control. This enum accepts the following values: BetweenLabels and CrossLabels.

See Also
  • argumentAxis.type - sets the type of the argument axis.
  • valueAxis.type - sets the type of the value axis.

endOnTick

Specifies whether to force the axis to start and end on ticks.

Type:

Boolean

Default Value: false

grid

Configures the grid.

Type:

Object

A grid is a set of mutually-crossing vertical and horizontal lines that stretch throughout the entire chart. Visually, grid lines can be considered extensions of major ticks. The grid improves the readability of chart data.

DevExtreme HTML5 Charts GridLines

The commonAxisSettings.grid object specifies common settings for all grid lines in the chart. To configure only those grid lines that descend from a particular axis, use the following objects.

Axis-specific settings override common settings.

See Also
  • commonAxisSettings.minorGrid - configures the minor grid built on minor ticks.

holidays

Dates to be excluded from the axis when workdaysOnly is true.

Type:

Array<Date | String>

|

Array<Number>

Default Value: undefined

See Also

hoverMode

Specifies chart elements to be highlighted when a user points to an axis label.

Type:

String

Default Value: 'none'
Accepted Values: 'allArgumentPoints' | 'none'

This option accepts one of the following values.

  • none
    Axis labels do not respond to pointing to them.
  • allArgumentPoints
    When a user points to a label on the argument axis, series points of the corresponding argument become highlighted.

Use the ArgumentAxisHoverMode enum to specify this option when the widget is used as an ASP.NET MVC 5 Control or a DevExtreme-Based ASP.NET Core Control. This enum accepts the following values: AllArgumentPoints and None.

See Also
  • commonSeriesSettings.point.hoverStyle - specifies the appearance of series points in the hover state. Applies to all series points.
  • series.point.hoverStyle - the same, but applies to the points of a particular series.

inverted

Inverts the axis.

Type:

Boolean

Default Value: false

When an axis is inverted (that is, when this option is set to true), its maximum and minimum values swap their places. As a result, axis values ascend in the opposite direction. Along with the axis, series also become inverted.

See Also

label

Configures the labels of the argument axis.

Type:

Object

Axis labels display the values of major axis ticks.

DevExtreme HTML5 Charts AxisLabels

See Also
  • commonAxisSettings.label - configures the labels of all axes in the widget.

logarithmBase

Specifies the value to be raised to a power when generating ticks for an axis of the "logarithmic" type.

Type:

Number

Default Value: 10

By default, ticks on a logarithmic axis are generated on a base of 10, i.e., 0.1, 1, 10, 100, 1000 etc. But you can specify the needed base using the logarithmBase option. For example, if you set this option to 5, the following ticks will be generated: 0.5, 5, 25, 125, 625, etc.

NOTE
This value should be greater than 1.

max Deprecated

Use the visualRange property instead.

Coupled with the min option, focuses the widget on a specific chart segment. Applies only to the axes of the "continuous" and "logarithmic" type.

Type:

Number

|

Date

|

String

Default Value: undefined

maxValueMargin

Controls the empty space between the maximum series points and the axis. Applies only to the axes of the "continuous" and "logarithmic" type.

Type:

Number

Default Value: undefined

By default, the axes extend slightly beyond their extrema generating an empty space between the axes and the minimum/maximum series points. It prevents cutting off parts of those points. To control this empty space, use the minValueMargin and maxValueMargin options. These options are used in the following formulas for the actual start and end axis values.

startAxisValue = minDataValue - (maxDataValue - minDataValue) * minValueMargin
endAxisValue = maxDataValue + (maxDataValue - minDataValue) * maxValueMargin

For example, consider that minDataValue is 1960 and maxDataValue is 2010. If you set the minValueMargin and maxValueMargin options to 0.1, the axis will start in 1955 and end in 2015.

startAxisValue = 1960 - (2010 - 1960) * 0.1 = 1960 - 50 * 0.1 = 1960 - 5 = 1955
endAxisValue = 2010 + (2010 - 1960) * 0.1 = 2010 + 50 * 0.1 = 2010 + 5 = 2015

String

Default Value: undefined

minorGrid

Configures the minor grid.

Type:

Object

In addition to the major grid built on major ticks, the Chart widget provides the minor grid built on minor ticks.

DevExtreme HTML5 Charts MinorGridLines

NOTE
Neither minor ticks, nor the minor grid can be displayed if the axis is of the "discrete" type.

The commonAxisSettings.minorGrid object specifies common settings for all minor grid lines in the chart. To configure only those grid lines that descend from a particular axis, use the following objects.

Axis-specific settings override common settings.

NOTE
Displaying the minor grid without the major grid may impair the readability of a chart. To prevent this situation, we recommend you use the minor grid only in conjunction with the major grid.

minorTick

Configures the appearance of minor axis ticks.

Type:

Object

Along with major ticks, the Chart widget supports minor ticks. They divide an axis segment limited by two neighboring major ticks.

DevExtreme HTML5 Charts MinorTicks

The commonAxisSettings.minorTick object specifies common settings for all minor ticks in the chart. To configure only those minor ticks that belong to a particular axis, use the following objects.

Axis-specific settings override common settings.

NOTE
Minor ticks cannot be displayed on an axis of the "discrete" type.
See Also
  • argumentAxis.minorTickInterval - specifies the minor tick interval of the argument axis.
  • valueAxis.minorTickInterval - specifies the minor tick interval of the value axis.

minorTickCount

Specifies how many minor ticks to place between two neighboring major ticks.

Type:

Number

Default Value: undefined

See Also
  • argumentAxis.minorTickInterval - specifies the interval between minor ticks. Has a higher priority than the minorTickCount option.

minorTickInterval

Specifies the interval between minor ticks. Applies only to the axes of the "continuous" type.

Type:

Number

|

Object

|

String

Default Value: undefined
Accepted Values: 'day' | 'hour' | 'millisecond' | 'minute' | 'month' | 'quarter' | 'second' | 'week' | 'year'

Minor ticks divide the segment between two neighboring major ticks into smaller segments. Minor ticks are generated automatically, unless the minorTickInterval option is set.

If the axis displays numbers, assign a number to this option. If the axis displays date-time values, assign one of the accepted string values or an object to this option. The object should contain one or several fields described in this section, for example:

jQuery
JavaScript
$(function() {
    $("#chartContainer").dxChart({
        // ...
        argumentAxis: {
            // ...
            minorTickInterval: { days: 5 }
        }
    });

minValueMargin

Controls the empty space between the minimum series points and the axis. Applies only to the axes of the "continuous" and "logarithmic" type.

Type:

Number

Default Value: undefined

By default, the axes extend slightly beyond their extrema generating an empty space between the axes and the minimum/maximum series points. It prevents cutting off parts of those points. To control this empty space, use the minValueMargin and maxValueMargin options. These options are used in the following formulas for the actual start and end axis values.

startAxisValue = minDataValue - (maxDataValue - minDataValue) * minValueMargin
endAxisValue = maxDataValue + (maxDataValue - minDataValue) * maxValueMargin

For example, consider that minDataValue is 1960 and maxDataValue is 2010. If you set the minValueMargin and maxValueMargin options to 0.1, the axis will start in 1955 and end in 2015.

startAxisValue = 1960 - (2010 - 1960) * 0.1 = 1960 - 50 * 0.1 = 1960 - 5 = 1955
endAxisValue = 2010 + (2010 - 1960) * 0.1 = 2010 + 50 * 0.1 = 2010 + 5 = 2015

opacity

Specifies how transparent the axis line should be.

Type:

Number

Default Value: undefined

This option accepts a value from 0 to 1, where 0 makes the axis line completely transparent, and 1 makes it opaque.

placeholderSize

Reserves a pixel-measured space for the axis.

Type:

Number

Default Value: null

The reserved space will be occupied by the axis line and axis labels.

DevExtreme HTML5 Charts AxisPlaceholder

singleWorkdays

Dates to be included on the axis when workdaysOnly is true.

Type:

Array<Date | String>

|

Array<Number>

Default Value: undefined

See Also

strips[]

Declares a collection of strips belonging to the argument axis.

Type:

Array<Object>

Cannot be used in themes.

A strip is a colored piece of the chart's background that highlights a range of values. Strips allow a viewer to see whether a certain series point falls in or out of a range.

DevExtreme HTML5 Charts Strips

Each object in the strips array configures a single strip. To limit a strip, set its startValue and endValue options. You may set only one of them, in which case the strip will not have a limit at one end. Note that setting the color option is also necessary for a strip to be displayed.

See Also
  • argumentAxis.stripStyle - specifies the appearance of those strips that belong to the argument axis.
  • commonAxisSettings.stripStyle - specifies the appearance of all strips in the widget.

stripStyle

Configures the appearance of strips.

Type:

Object

DevExtreme HTML5 Charts Strips

The commonAxisSettings.stripStyle object specifies common settings for all strips in the chart. To configure only those strips that belong to a particular axis, use the following objects.

To configure individual strips, use the following arrays of objects.

Individual settings override axis-specific settings which, in their turn, override common settings.

tick

Configures the appearance of major axis ticks.

Type:

Object

Ticks divide an axis into sections that measure off values on this axis.

DevExtreme HTML5 Charts MajorTicks

The commonAxisSettings.tick object specifies common settings for all major ticks in the chart. To configure only those major ticks that belong to a particular axis, use the following objects.

Axis-specific settings override common settings.

See Also
  • argumentAxis.tickInterval - specifies the tick interval of the argument axis.
  • valueAxis.tickInterval - specifies the tick interval of the value axis.
  • commonAxisSettings.minorTick - customizes the appearance of minor ticks.

tickInterval

Specifies the interval between major ticks.

Type:

Number

|

Object

|

String

Default Value: undefined
Accepted Values: 'day' | 'hour' | 'millisecond' | 'minute' | 'month' | 'quarter' | 'second' | 'week' | 'year'

Major ticks divide an axis into segments, thus improving the viewer's perception of visualized data. Major ticks are generated automatically, unless the tickInterval option is set.

If the axis displays numbers, assign a number to this option. If the axis displays date-time values, assign one of the accepted string values or an object to this option. The object should contain one or several fields described in this section, for example:

jQuery
JavaScript
$(function() {
    $("#chartContainer").dxChart({
        // ...
        argumentAxis: {
            // ...
            tickInterval: { days: 5 }
        }
    });

    ],
    // ...
})

When you use an axis of the "logarithmic" type, ticks are generated on a base of powers. For example, assuming that the logarithm base is 10 and the tick interval is 1, ticks are generated at 10-2, 10-1, 100, 101, 102, 103, etc. If the tick interval becomes 2, ticks are generated at 10-1, 101, 103, etc.

When using the widget as an ASP.NET MVC 5 Control or a DevExtreme-Based ASP.NET Core Control, specify this option using the VizTimeInterval enum. This enum accepts the same values, but they start with an upper-case letter, for example, 'day' becomes Day.

See Also
  • argumentAxis.tick - configures the appearance of major ticks.
  • argumentAxis.minorTickInterval - specifies the interval between minor ticks.

title

Configures the axis title.

Type:

String

|

Object

The axis title is a short text displayed alongside the axis. Usually, the axis title shows units of measurement for arguments displayed by the axis. You can put any text in the axis title though.

DevExtreme HTML5 Charts AxisTitles

If you assign an object to the title option, specifying the text field of this object is necessary for the axis title to be displayed. Besides the object, the title option accepts a string, thus providing a shortcut for setting the axis title. Therefore, this:

title: 'Axis Title'

is the same as this:

title: {
    text: 'Axis Title'
}
See Also
  • commonAxisSettings.title - specifies the appearance of all axis titles in the widget.

type

Specifies the type of the argument axis.

Type:

String

Default Value: undefined
Accepted Values: 'continuous' | 'discrete' | 'logarithmic'

The argument axis can have one of the following types.

  • Continuous
    Displays numeric and date-time arguments. To divide this axis into intervals, use the tickInterval option.
  • Discrete
    Displays string arguments called "categories". To sort them, use the categories array.
  • Logarithmic
    Displays numeric arguments. Each argument is the logarithmBase value raised to some power. For example, logarithmBase equaling to 10 produces the following arguments: 10-2, 10-1, 100, 101, 102, etc. The logarithmic axis is useful when you visualize a dataset of rapidly-growing values.

Normally, there is no need to specify this option, because the axis type is determined automatically depending on the type of arguments. However, you may force the use of a specific axis type, for example, to employ the "discrete" axis type with numeric or date-time arguments.

Use the AxisScaleType enum to specify this option when the widget is used as an ASP.NET MVC 5 Control or a DevExtreme-Based ASP.NET Core Control. This enum accepts the following values: Discrete, Continuous, and Logarithmic.

valueMarginsEnabled

Adds an empty space between the axis and the minimum and maximum series points.

Type:

Boolean

Default Value: true

By default, the argument axis extends slightly beyond its extrema. It prevents cutting off parts of the minimum and maximum series points. To disable this feature, set the valueMarginsEnabled option to false.

Array<Number | String | Date>

Raised Events: onOptionChanged
Cannot be used in themes.

This option accepts one of the following:

  • A two-item array

    Specifies the range's start and end. The array can contain a pair of numeric, string, or date-time values, depending on the axis's argumentType. You can also set one of the array values to null to specify an open-ended range.

    visualRange: [50, 70]
    // Open-ended range
    visualRange: [null, 70]
  • An object with the startValue and endValue fields

    An alternative to the two-item array.

    visualRange: {
        startValue: 50,
        endValue: 70
    }
    // Open-ended range
    visualRange: {
        startValue: null,
        endValue: 70
    }
  • An object with the length and a startValue or endValue field

    Specifies the range using a start or end value and length.

    visualRange: {
        startValue: 50,
        length: 20
    }
    // ===== or =====
    visualRange: {
        endValue: 70,
        length: 20
    }
  • An object with the length field

    Sets the range of the specified length using the last axis value as the end value.

    visualRange: {
        length: 20
    }

visualRangeUpdateMode

Specifies how the axis's visual range should behave when chart data is updated.

Type:

String

Default Value: 'auto'
Accepted Values: 'auto' | 'keep' | 'reset' | 'shift'

The following modes are available:

  • "shift"
    The visual range moves to the axis's end. The range's length does not change.

  • "reset"
    The visual range becomes equal to the whole range.

  • "keep"
    The visual range does not change.

  • "auto"
    The applied mode changes depending on the visual range's position on the axis:

    • at the start or middle, then "keep";
    • at the end, then "shift";
    • if set to view the whole range, then "reset" (the visual range remains equal to the whole range).

    wholeRange: [50, 70]
    // Open-ended range
    wholeRange: [null, 70]
  • An object with the startValue and endValue fields

    An alternative to the two-item array.

    wholeRange: {
        startValue: 50,
        endValue: 70
    }
    // Open-ended range
    wholeRange: {

        endValue: 70
    }
  • An object with the length and a startValue or endValue field

    wholeRange: {
        startValue: 50,
        length: 20
