Tooltips display information about the area hovered by a cursor. When viewing a Chart, tooltips display information about data points and labels when you hover the cursor over a data series.

You can define tooltips for the chart's data point (viewed in HTML5 Viewer) by using expressions in the Tooltip field of the Series Values of the Chart Data dialog. You can also set a tooltip for a Chart in code by using the ToolTip property.
If the Tooltip property is set, the label value of the current category group is displayed with the data points. In case of a nested grouping, the lowest category group value is displayed.

The following chart types, which do not support any interactivity feature, also do not support tooltips for charts in the HTML5 Viewer.

Note: This topic uses the HTML5Viewer sample located in [User Documents folder]\GrapeCity Samples\ActiveReports 13 folder.

  1. Open the HTML5Viewer sample.
  2. In the Solution Explorer, go to the Reports folder and open SalesDashboard.rdlx.
  3. In the Report Explorer, select the chSales_Column chart.

  5. Go to the Series Values page and select Sales.
  6. In the Tooltip field, enter the following expression:

    ="Sales: " & Sum(Fields!Sales.Value)

  7. On the Series Values page, select TargetValue.
  8. In the Tooltip field, enter the following expression:

    ="Target : " & Fields!TargetValue.Value

  9. Click OK and run the application. The tooltips are displayed on hovering the Chart series.
