Intensity graph gridlines not visible

[cdouillet]

Hi to all,

I cannot seem to get to show the grid lines on an intensity graph. They do show anywhere there is no data, but where there is data they are hidden. Is this a bug or am I doing something wrong?

    griStats.Plot(stats)
    intensityPlot.PixelInterpolation = True

    griStats.XAxes(0).MajorDivisions.GridLineStyle = UI.LineStyle.Solid
    griStats.XAxes(0).MajorDivisions.GridColor = Color.Black
    griStats.XAxes(0).MajorDivisions.Base = 0
    griStats.XAxes(0).MajorDivisions.Interval = 1
    griStats.XAxes(0).MajorDivisions.GridVisible = True
    griStats.XAxes(0).Range = New UI.Range(0, UBound(twa))

    griStats.YAxes(0).MajorDivisions.GridLineStyle = UI.LineStyle.Solid
    griStats.YAxes(0).MajorDivisions.GridColor = Color.Black
    griStats.YAxes(0).MajorDivisions.Base = 0
    griStats.YAxes(0).MajorDivisions.Interval = 1
    griStats.YAxes(0).Range = New UI.Range(0, UBound(tws))
    griStats.YAxes(0).MajorDivisions.GridVisible = True

Thanks for your help,

It looks very much like a z-order problem or something of the sort.

Hey there,

Try this. Hook on to the IntensityGraph.AfterDrawPlot event.

private void intensityGraph1_AfterDrawPlot(object sender, NationalInstruments.UI.AfterDrawIntensityPlotEventArgs e)
{
    intensityGraph1.DrawGridLines(new NationalInstruments.UI.ComponentDrawArgs(e.Graphics, e.Bounds));
}

Hope this helps.

That worked great, thank you very much.

Hi, is this still the only way?  This solution is from 2011 so perhaps there's a setting instead of this "hack"?

By the way, I am using WPF so not even sure if this solution will work.

Thank you!
