For example, suppose the query parameters for the hot spot is:
| x=0&xLabel=Mon&dataSet=0&dataSetName=Revenue&value=100 |
The WebHotSpotEventArgs 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 query parameters attributes, the WebChartViewer.GetPostBackURL can also introduce an additional attribute "cookie" into the table.
