Cursor lines in chart

Question

I'm using a chart control within a C# windows forms project. What I would like is to have dotted lines follow my mouse around as it moves about the chart. I may make the lines centered about the cursor or the data point; at this point I am flexible. I've included a screen shot of what it is I'm looking for below. So here you can see black dotted lines (the cursor doesn't appear because it was a screen grab). I already have a mouseMove event but I'm not sure which code to include in that mousemove to get this working (right now it only works when I click the mouse, but I think taht is just because I have CursorX.IsUserSelection enabled). I already formatted the lines in the chart creation function but is there some CursorX.LineEnable function or something similar? I've not been able to find any. I know that I could accomplish this with a painted object but I was hoping to avoid the hassle. Thanks in advance! I'll include my line formatting below. This is in the chart creation section.…

Accepted Answer

Inside the chart's MouseMove event handler, you can do the following to make the cursor move:

```
private void chData_MouseMove(object sender, MouseEventArgs e)
{
    Point mousePoint = new Point(e.X, e.Y);

Chart.ChartAreas[0].CursorX.SetCursorPixelPosition(mousePoint, true);
    Chart.ChartAreas[0].CursorY.SetCursorPixelPosition(mousePoint, true);

// ...
}
```

This is the documentation for the SetCursorPixelPosition method: http://msdn.microsoft.com/en-us/library/system.windows.forms.datavisualization.charting.cursor.setcursorpixelposition.aspx
