Hi,

The Horizontal/Vertical steps control how much to offset the data point if the user presses the control key and starts to move the data point using the keyboard. You can intercept the drag event of the tool and snap the data point to a custom location.

Hi,

Please see the following code. Why the PointDragTool is still moving the data point in a continuous manner even though I've set the step. Is there any switch to turn on?

private void Form1_Load(object sender, EventArgs e)
{
NChart chart = nChartControl1.Charts[0];
NLineSeries lines = (NLineSeries)chart.Series.Add(SeriesType.Line);
lines.UseXValues = true;
lines.AddDataPoint(new NDataPoint(1,10));
lines.AddDataPoint(new NDataPoint(2.2,20));
lines.AddDataPoint(new NDataPoint(2.8,15));

NSelectorTool selector = new NSelectorTool();
nChartControl1.Controller.Tools.Add(selector);
NDataPointDragTool dataPointDragTool = new NDataPointDragTool();
dataPointDragTool.HorizontalStep = 5;
dataPointDragTool.VerticalStep = 5;
nChartControl1.Controller.Tools.Add(dataPointDragTool);
}

Thank you very much!

Enjoyear
