In NOV Chart for .NET all chart elements (axes, series, datapoints etc.) derive from the NChartElement base class, which provides support for Tooltips and Cursors on a per element basis.
Changing the Tooltip
In order to show a tooltip for a specific chart element you need to change its Tooltip property. The following code snippet show how to create a bar series with two data point that have an associated tooltip:
C# |
Copy Code
|
---|---|
NBarSeries bar = new NBarSeries(); NBarDataPoint dataPoint1 = new NBarDataPoint(10); NBarDataPoint dataPoint2 = new NBarDataPoint(20); chart.Series.Add(bar); |
Changing the Mouse Cursor
By default the mouse cursor applied on all chart element is the default mouse cursor. If you wish to change that for a specific chart element you need to assign a new cursor to the Cursor property of the element:
C# |
Copy Code
|
---|---|
someChartElement.Cursor = new NCursor(ENPredefinedCursor.Hand); |
