JavaScript/jQuery Chart - FullStackedSplineSeries

All the settings in this section are specified as follows:

• The commonSeriesSettings object
  Specifies settings for all series in a Chart.

• The commonSeriesSettings.fullstackedspline object
  Specifies settings for all series of the fullstackedspline type.

• An object in the series array
  Specifies settings for an individual series.

Displaying all the points of a Chart with many series points can affect performance. In this case, 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 property to true.

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

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.

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.

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

This property supports the following colors:

• Hexadecimal colors
• RGB colors
• RGBA colors
• Predefined/cross-browser color names
• Predefined SVG colors
• Paint server address

You can also specify a custom pattern or gradient instead of a plain color. Call the registerPattern() or registerGradient() method to obtain a fill ID. Assign that value to the fillId field.

This functionality is available for the following Chart series:

• Area
• Stacked area
• Full-stacked area
• Spline area
• Stacked spline area
• Full-stacked spline area
• Range area
• Step area
• Bar
• Stacked bar
• Full-stacked bar
• Range bar
• Bubble

  The border is displayed using dashes.

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

When a user points to a series, it may react in one of the following ways depending on the value of the hoverMode property.

hoverMode	Result
"nearestPoint"
"includePoints"
"excludePoints"
"none"

See Also

• hoverStyle - specifies the appearance of series in the hover state.
• point.hoverMode - specifies the hover mode of series points.

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.

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 property to true.

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.

$(function() {
    $("#chartContainer").dxChart({
        // ...
        series: [{
            label: {
                // Settings for all point labels of an individual series

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 property. Once this limit is exceeded, all point labels of the series will be hidden.

If this property is not specified, the series will belong to the default pane.

• panes - declares a collection of panes.

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

See Also

• customizePoint - сustomizes the appearance of an individual series point.

When a user selects a series, it may react in one of the following ways depending on the value of the selectionMode property.

selectionMode	Result
"includePoints"
"excludePoints"
"none"

See Also

• seriesSelectionMode - specifies whether only one or several series can stay selected.
• series.selectionStyle - specifies the appearance of a series in the selected state.
• series.point.selectionMode - specifies the selection mode of series points.
• seriesSelectionChanged - an event that fires after the selection state of a series has been changed.

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.

This property allows you to associate virtually any required data with a series point. This data will be stored in the tag field of the Point object.

Commonly, a chart contains several series, and many of them have the same tagField value. In this case, specify the tagField property in the commonSeriesSettings object. If a series must have a unique tagField value, specify the same property, but do so in the series object within the series array.

See Also

• series.tag - associates data with an entire series.

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.

• Series.show() - shows the series at runtime.
• Series.hide() - hides the series at runtime.
