Xceed Chart for WinForms can change the mouse cursor when it passes over chart elements. This is very useful when you want to visually prompt the end-user that something will happen when a chart element is clicked. To notify the control to change the mouse cursor when the mouse moves over the chart, you must add an object of type CursorChangeInteractivityOperation to the interactivity collection:
| VB.NET |
|
chartControl1.InteractivityOperations.Add(New CursorChangeInteractivityOperation())
|
| C# |
|
chartControl1.InteractivityOperations.Add(new CursorChangeInteractivityOperation());
|
By default, chart elements do not change the mouse cursor. The following example changes the cursor to "hand" when the mouse passes over a data item:
| VB.NET |
|
' init the values for the tooltip properties
chartControl.InteractivityOperations.Add(New CursorChangeInteractivityOperation())
Dim chart As Chart = CType((chartControl.Charts(0)), Chart)
' Create a bar series
Dim bar As BarSeries = CType(chart.Series.Add(SeriesType.Bar), BarSeries)
bar.BarStyle = BarStyle.CutEdgeBar
bar.Legend.Mode = SeriesLegendMode.DataPoints
bar.Values.Add(20.0)
bar.Values.Add(60.0)
bar.Values.Add(50.0)
bar.Values.Add(80.0)
bar.Values.Add(60.0)
bar.Interactivity.CursorMode = SeriesCursorMode.DataPoints
bar.Interactivity.Cursors.Add(CType(CursorType.Hand, Object))
bar.Interactivity.Cursors.Add(CType(CursorType.Hand, Object))
bar.Interactivity.Cursors.Add(CType(CursorType.Hand, Object))
bar.Interactivity.Cursors.Add(CType(CursorType.Hand, Object))
bar.Interactivity.Cursors.Add(CType(CursorType.Hand, Object))
' set some fill effects in the collection.
bar.Appearance.FillMode = AppearanceFillMode.DataPoints
Dim fillEffect As FillEffect = New FillEffect(Color.Red)
bar.Appearance.FillEffects.Add(fillEffect)

// init the values for the tooltip properties
chartControl.InteractivityOperations.Add(new CursorChangeInteractivityOperation());
Chart chart = (Chart)(chartControl.Charts[0]);
// Create a bar series
BarSeries bar = (BarSeries)chart.Series.Add(SeriesType.Bar);
bar.BarStyle = BarStyle.CutEdgeBar;
bar.Legend.Mode = SeriesLegendMode.DataPoints;
bar.Values.Add(20.0);
bar.Values.Add(60.0);
bar.Values.Add(50.0);
bar.Values.Add(80.0);
bar.Values.Add(60.0);
bar.Interactivity.CursorMode = SeriesCursorMode.DataPoints;
bar.Interactivity.Cursors.Add((object)CursorType.Hand);
bar.Interactivity.Cursors.Add((object)CursorType.Hand);
bar.Interactivity.Cursors.Add((object)CursorType.Hand);
bar.Interactivity.Cursors.Add((object)CursorType.Hand);
bar.Interactivity.Cursors.Add((object)CursorType.Hand);
// set some fill effects in the collection.
bar.Appearance.FillMode = AppearanceFillMode.DataPoints;
FillEffect fillEffect = new FillEffect(Color.Red);
bar.Appearance.FillEffects.Add(fillEffect);
