Public Property LegendMapAreaAttributes As String

Visual Basic (Usage)	Copy Code
Dim instance As DataPointAttributes Dim value As String   instance.LegendMapAreaAttributes = value   value = instance.LegendMapAreaAttributes

public string LegendMapAreaAttributes {get; set;}

Return Value

A string expression representing the map area attributes of a default legend item. Defaults to a zero-length string.

The following sample specifies a client-side javascript function to execute when the user clicks on the legend item for a series named Series1.

Visual Basic	Copy Code
Chart1.Series("Series1").LegendMapAreaAttributes = "OnClick=javascript:MyFunction()"

Pie and doughnut charts by default will display each plotted data point in the legend, and the default text for each legend entry is the name of the data point. All other chart types will display plotted series in the legend in the same manner.

Setting this property will automatically result in a client-side image map being created, and a map area will be created for the legend item with the attribute string appended to the <MAP> tag. Since the entire string is appended to the <MAP> tag multiple attributes should be separated with a space.

LegendMapAreaAttributes can be used in conjunction with the LegendHref property to specify map area attributes (e.g. Target= _Blank) as well as client-side event handlers (e.g. OnClick="MyEvent()").

Setting this property will have no effect if the Chart object's MapEnabled property is set to False (True by default).

IMPORTANT: To create an image map this way the RenderType property of the Chart object MUST be RenderType.ImageTag. It is possible to create an image map when using binary streaming, but another technique must be used. Refer to the Client-Side Mapping and Binary Streaming topic for further details.

Special keywords may be used when setting this property, and each keyword will be replaced with some type of data from the applicable chart element. Refer to the following table for a listing of all available keywords:
