Data Pan Tool

The Data Pan feature allows you to scroll the chart contents using the mouse when the chart axes are configured to use paging (which is the case after a Data Zoom operation for example).


You enable the data pan feature by adding an object of type NDataPanTool to the NToolCollection of the control:
C#
Copy Code
NDataPanTool dataPanTool = new NDataPanTool();
chartControl.Controller.Tools.Add(dataPanTool);
Visual Basic
Copy Code
Dim dataPanTool As NDataPanTool =  New NDataPanTool()
chartControl.Controller.Tools.Add(dataPanTool)

Configuring the axes on which the data pan tool operates is done by touching the HorizontalAxisId and VerticalAxisId properties.

The NDataPanTool tool has a property called RepaintChartWhileDragging controlling whether the control to repaint while dragging occurs. This leads to better visual feedback for the user at the expense of higher CPU load. This property is enabled by default but you can disable it at any time:

C#
Copy Code
dataPanTool.RepaintChartWhileDragging = false;
Visual Basic
Copy Code
dataPanTool.RepaintChartWhileDragging = False
