[WPF]how to set cursor on the position I clicked on the graph?

[darkeria]

Hello,

I used to do that in a winform project by use thefollowing function:

PlotAreaMouseDownCwgraph(short* Button, short* Shift, VARIANT* XPos, VARIANT* YPos)

But in a wpf graph, the PlotAreaMouseLeftButtonDown event seems not contain the xpos and ypos. I wrote the following code and got a wrong result:

        void m_Graph_PlotAreaMouseLeftButtonDown(object sender, MouseButtonEventArgs e)
        {
            if (m_Graph.DefaultInteraction == GraphInteraction.None)
            {
                Point p = m_Graph.GetPlotAreaPosition(e);
                cursor.SetRelativePosition(p);
            }
        }

The value returned by GetPlotAreaPosition is a screen value (the documentation is a bit confusing here; I have created a task to update it).

To use SetRelativePosition, you can convert the screen value to a relative value by calling the ScreenToRelative on the graph.

Or you can pass the value returned by GetPlotAreaPosition directly to the SetScreenPosition method on the cursor.
