jQuery Chart - series

Specifies options for Chart widget series.

Default Value: undefined
Cannot be used in themes.

A series represents a grouping of related data points. The most important characteristic of a series is its type, which determines a particular visual representation of data. You can find more details on each series type in the corresponding topics in the Series help section.

To define a single series, assign an object defining the series to the series configuration object. In the series' object, specify the series type, data source fields, the appearance of the series points and other options.

To show several series, specify series as an array of objects defining series. If you need to set similar values to properties of several series, use the commonSeriesSettings configuration object. It exposes the properties that can be specified for all series at once and for all series of a particular type at once. Note that the values specified for a series individually (in the series array) override the values that are specified for all series (in the commonSeriesSettings object).

NOTE
This option is necessary. If you do not need to specify any of the options within the series object (e.g., when you have specified them within the commonSeriesSettings object), assign at least an empty object to the series field.

aggregation

Configures data aggregation for the series.

Type:

Object

If the Chart contains many series points, displaying all of them may lower its performance. In this case, it is better to aggregate the series points, or replace a group of them with a single point. The group includes only those points that fall within the same interval on the argument axis. See aggregationInterval and aggregationGroupWidth for details on dividing the axis into intervals.

The Chart provides several aggregation methods, which differ depending on the series type, and a capability to implement a custom aggregate function. To enable data aggregation for the series, set the aggregation.enabled option to true.

See Also

argumentField

Specifies which data source field provides arguments for series points.

Type:

String

Default Value: 'arg'
Cannot be used in themes.

In the Cartesian coordinate system, each point is characterized by a pair of coordinates (X, Y). In the Chart widget, X's are provided by the argumentField; Y's are provided by the valueField.

NOTE
Certain series types have more than one value field, or require additional data fields to be set. Refer to the valueField option description for details.

Commonly, a chart contains several series, and many of them have the same argument field. In this case, assign the name of this field to the argumentField property of the commonSeriesSettings object. If a series must have a unique argument field, specify the same property, but do so in the series object within the series array.

axis

Binds the series to a value axis.

Type:

String

Default Value: undefined

When there are multiple value axes in a chart, series need to know exactly which axis they are bound to. By default, all of them are bound to the first axis in the valueAxis array. To bind a series to another axis, assign the name of the axis to the axis series property.

barOverlapGroup

Allows you to group bar series so that bars with the same argument overlap.

Type:

String

Default Value: undefined
This member is exposed by the following entities:

Set this option to identical values for the series you want to collect in a single group.

The following image shows a regular bar chart with two series...

DevExtreme Chart: Regular bar chart

...and here the same series are collected in a barOverlapGroup:

DevExtreme Chart: Bar chart with barOverlapGroup applied

View Demo

barPadding

Controls the padding and consequently the width of all bars in a series using relative units. Ignored if the barWidth option is set.

Type:

Number

Default Value: undefined
This member is exposed by the following entities:

This option accepts a value from 0 to 1 that specifies the correlation between the empty space on a bar's sides and the bar's width: 0 - the bar occupies the whole allocated space; 1 - virtually hides the bar creating a lot of empty space.

See Also

barWidth

Specifies a fixed width for all bars in a series, measured in pixels. Takes precedence over the barPadding option.

Type:

Number

Default Value: undefined
This member is exposed by the following entities:

A bar's maximum width is limited. In single-series charts, it cannot be greater than the interval between two major ticks. In multi-series charts, it depends on the number of bars in the parent group and this group's actual width. See the Specify the Bar Width article for more information.

See Also

border

Configures the series border (in area-like series) or the series point border (in bar-like and bubble series).

Declared in commonSeriesSettings, the border settings apply to all series in the chart. Declared in a series configuration object, the border settings apply to this particular series only. The series-specific border settings override the common ones.

closeValueField

Specifies which data source field provides close values for points of a financial series.

Type:

String

Default Value: 'close'
This member is exposed by the following entities:
Cannot be used in themes.

Each point in a financial series has one argument and four values. Arguments are provided by the argumentField; values are provided by the openValueField, closeValueField, highValueField and lowValueField.

If you use a series template, specify the value field properties in the commonSeriesSettings object. Otherwise, do this in the series object within the series array.

color

Specifies the color of the series.

Type:

String

Default Value: undefined

This option supports the following colors:

Specified in the commonSeriesSettings object, this option colors all series in the chart. To color an individual series, specify this option in the series object within the series array.

cornerRadius

Makes bars look rounded. Applies only to bar-like series.

Type:

Number

Default Value: 0
This member is exposed by the following entities:

dashStyle

Specifies the dash style of the series line. Applies only to line-like series.

Type:

String

Default Value: 'solid'
Accepted Values: 'dash' | 'dot' | 'longDash' | 'solid'

The following dash styles are available:

  • solid
    The border is a solid, continuous line.

  • longDash
    The border is displayed using long dashes.

  • dash
    The border is displayed using dashes.

  • dot
    The border is displayed using dots.

  • Any combination of 'longDash', 'dash' and 'dot'
    The border is displayed by repeating the specified combination. For instance, 'dashdotdash'.

Use the DashStyle 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: Solid, LongDash, Dash, and Dot.

highValueField

Specifies which data source field provides high values for points of a financial series.

Type:

String

Default Value: 'high'
This member is exposed by the following entities:
Cannot be used in themes.

Each point in a financial series has one argument and four values. Arguments are provided by the argumentField; values are provided by the openValueField, closeValueField, highValueField and lowValueField.

If you use a series template, specify the value field properties in the commonSeriesSettings object. Otherwise, do this in the series object within the series array.

hoverMode

Specifies series elements to be highlighted when a user points to a series.

Type:

String

Accepted Values: 'allArgumentPoints' | 'allSeriesPoints' | 'excludePoints' | 'includePoints' | 'nearestPoint' | 'none' | 'onlyPoint'

Depending on the series type, this option accepts different values. For information on them, visit the Series Types section, choose the employed series type and refer to its hoverMode option description.

hoverStyle

Configures the appearance adopted by the series when a user points to it.

Type:

Object

Declared in commonSeriesSettings, hoverStyle applies to all series in the chart. Declared in a series configuration object, hoverStyle applies to this particular series only. The series-specific hoverStyle overrides the common one.

ignoreEmptyPoints

Specifies whether the series should ignore null data points.

Type:

Boolean

Default Value: false

Data points that have the null value do not produce actual series points. Because of this, series may be drawn with unnecessary gaps where missing points should have been. To remove these gaps, set the ignoreEmptyPoints option to true.

innerColor

Specifies a filling color for the body of a series point that visualizes a non-reduced value. Applies only to candlestick series.

Type:

String

Default Value: '#ffffff'
This member is exposed by the following entities:

See Also
  • reduction - specifies the price reduction options for financial series.
  • color - colors the frame of a series point in candlestick series.

label

Configures point labels.

Type:

Object

Declared in commonSeriesSettings, the label settings apply to all point labels in the chart. Declared in a series configuration object, the label settings apply only to the point labels that belong to this particular series. The series-specific label settings override the common ones.

Type:

String

Default Value: 'low'
This member is exposed by the following entities:
Cannot be used in themes.

Each point in a financial series has one argument and four values. Arguments are provided by the argumentField; values are provided by the openValueField, closeValueField, highValueField and lowValueField.

If you use a series template, specify the value field properties in the commonSeriesSettings object. Otherwise, do this in the series object within the series array.

maxLabelCount

Specifies a limit for the number of point labels.

Type:

Number

Default Value: undefined

If the number of points in a series increases over time, there comes a time when it becomes so massive that displaying labels for them makes the chart too cluttered. In this instance, to keep the chart clear to the viewer, specify a limit for the number of point labels using the maxLabelCount option. Once this limit is exceeded, all point labels of the series will be hidden.

minBarSize

Specifies the minimal possible height (or length if the chart is rotated) of a bar in pixels. Applies only to bar-like series.

Type:

Number

Default Value: undefined
This member is exposed by the following entities:

If the disparity between the smallest and largest values in the data source is considerable, small values are visualized by tiny bars that may be difficult to interact with. In this case, specify the minimal possible height (or length if the chart is rotated) for bars using the minBarSize option.

This member is exposed by the following entities:

Each point in a financial series has four values or "prices": high, low, open and close. To mirror the changes on the market more clearly, the widget compares the price of every point with the price of the previous point. Those points whose price has decreased are painted in a specific color. To specify whether high, low, open or close prices of points should be compared, use the level option.

selectionMode

Specifies series elements to be highlighted when a user selects a series.

Type:

String

Accepted Values: 'allArgumentPoints' | 'allSeriesPoints' | 'excludePoints' | 'includePoints' | 'none' | 'onlyPoint'

Depending on the series type, this option accepts different values. For information on them, visit the Series Types section, choose the employed series type and refer to its selectionMode option description.

selectionStyle

Configures the appearance adopted by the series when a user selects it.

Type:

Object

NOTE
Though not provided out of the box, the selection capability can be implemented using the widget API. Refer to the onPointClick option description for details.

Declared in commonSeriesSettings, selectionStyle applies to all series in the chart. Declared in a series configuration object, selectionStyle applies to this particular series only. The series-specific selectionStyle overrides the common one.

showInLegend

Specifies whether to show the series in the legend or not.

Type:

Boolean

Default Value: true

sizeField

Specifies which data source field provides size values for bubbles. Required by and applies only to bubble series.

Type:

String

Default Value: 'size'
This member is exposed by the following entities:

Each point in a bubble series has an argument, a regular value and a size value. Arguments are provided by the argumentField; regular values are provided by the valueField; size values are provided by the sizeField.

Size values do not specify the real sizes of bubbles directly, they only define the sizes of bubbles in relation to each other. Apart from a size value, the real, pixel-measured size of a bubble depends on the minBubbleSize and maxBubbleSize values and the size of the pane.

Commonly, a chart contains several series, and many of them have the same size field. In this case, assign the name of this field to the sizeField property of the commonSeriesSettings object. If a series must have a unique size field, specify the same property, but do so in the series object within the series array.

stack

Specifies which stack the series should belongs to. Applies only to stacked bar and full-stacked bar series.

Type:

String

Default Value: 'default'
This member is exposed by the following entities:

valueErrorBar

Configures error bars.

Type:

Object

This member is exposed by the following entities:

Error bars are used on charts to indicate an error or an uncertainty in a reported measurement. They give a general idea of how precise the measurement is.

DevExtreme HTML5 Charts ErrorBars

Error bars can be generated either from concrete or calculated values. To generate one error bar, two values, high and low, are needed. If the data source of your chart provides concrete high and low values, assign the required data source fields to the highValueField and lowValueField options.

Alternatively, error bar values can be calculated according to an algorithm. In this case, choose the required algorithm using the type option, and specify the value to be used in calculation using the value option.

NOTE
Error bars are available for axes of the numeric type only.

valueField

Specifies which data source field provides values for series points.

In the Cartesian coordinate system, each point is characterized by a pair of coordinates (X, Y). In a common case, X's are provided by the argumentField; Y's are provided by the valueField.

Certain series types require more than one value field, because their points are characterized by a larger number of coordinates. These series types are:

  • Range-like series types
    Range bar and range area require two value fields: rangeValue1Field and rangeValue2Field.
  • Financial series types
    Stock and candlestick require four value fields: openValueField, closeValueField, highValueField and lowValueField.

If you use a series template, specify the value field properties in the commonSeriesSettings object. Otherwise, do this in the series object within the series array.

visible

Specifies whether the series is visible or not.

Type:

Boolean

Default Value: true

NOTE
When the series is invisible, the marker of its legend item is faded.
See Also
  • Series.show() - shows the series at runtime.
  • Series.hide() - hides the series at runtime.

width

Specifies the width of the series line in pixels. Applies only to line-like series.
