WPFHotSpotEventArgs

WPFHotSpotEventArgs is used in various hot spot events of the WPFChartViewer control to represent attributes associated with the hot spot. These attributes come from query parameters in the image map that defines the hot spot.

For example, suppose the query parameters for the hot spot is:

x=0&xLabel=Mon&dataSet=0&dataSetName=Revenue&value=100

The WPFHotSpotEventArgs object will contain the following attributes.

Attribute	Value
x	0
xLabel	Mon
dataSet	0
dataSetName	Revenue
value	100

If there are two attributes with the same name in the query parameters, they will be merged into one attribute, with the values appended together, delimited using the ASCII unit separator character (ASCII code 31).

In addition to the attributes due to query parameters, the WPFHotSpotEventArgs object contains three additional attributes as follows:

The path attribute reflecting the path portion of the URL in the <AREA> tag that defines the hot spot.
The coords attribute reflecting the coords attribute of the <AREA> tag that defines the hot spot.
The title attribute reflecting the title attribute of the <AREA> tag that defines the hot spot.

WPFHotSpotEventArgs is a subclass of System.Windows.Input.MouseEventArgs. Therefore, it also supports all properties of MouseEventArgs. For instance, you can use MouseEventArgs to determine which mouse button is pressed in a MouseDownHotSpot event.
