Namespace: DevExpress.Web.Bootstrap
Assembly: DevExpress.Web.Bootstrap.v18.2.dll
Declaration
Property Value
| Type | Default | Description |
|---|---|---|
| String | String.Empty | A string specifying a JavaScript function that returns an object providing information about the series point. |
Remarks
By default, all series points in a chart are identical, but you can specify a unique appearance for individual points using the OnClientCustomizePoint function. This function should return an object with options that will be changed for a certain point. See the BootstrapChartPointSettings object for information about all options available for changing.
Note
The BootstrapChartLegendSettings.HoverMode and BootstrapChartBase.PointSelectionMode properties cannot be changed using the OnClientCustomizePoint function, because they do not have anything to do with the appearance of series points.
The OnClientCustomizePoint function accepts an object providing information about the series point that the label belongs to. This object contains the following fields.
Field | Description |
|---|---|
argument | The argument of the series point. |
value | The value of the series point. In the range bar and range area series, the value field is replaced by the BootstrapChartRangeSeriesBase.RangeValue1Field and BootstrapChartRangeSeriesBase.RangeValue2Field fields. In the financial series (candlestick and stock), the value field is replaced by the BootstrapChartFinancialSeriesBase.OpenValueField, BootstrapChartFinancialSeriesBase.CloseValueField, BootstrapChartFinancialSeriesBase.LowValueField and BootstrapChartFinancialSeriesBase.HighValueField fields. |
tag | The tag of the series point. |
series | The series that includes the series point. |
index | The index of the series point in the points array. |
