Plotting x-axis samples in descending order

Hi.
I have version 2.0 of Steema. Is it possible to plot X,Y double values such that from left to right the x-axis labels are displayed in descending order?
So for example if I have four X,Y samples as follows:
X Y
100 20
60 24
0 30
-50 22
then the x-axis labels would be shown (from left to right) starting at 100 and ending at -50.
Thanks,
Ben.

You could invert the bottom axis, e.g.
Code: Select all
Line series;
private void InitializeChart()
{
tChart1.Aspect.View3D = false;
series = new Line(tChart1.Chart);
series.Add(100, 20);
series.Add(60, 24);
series.Add(0, 30);
series.Add(-50, 20);
}
private void button1_Click(object sender, EventArgs e)
{
tChart1.Axes.Bottom.Inverted = !tChart1.Axes.Bottom.Inverted;
}

Wow thanks Christopher - easy once you know how!
Are there any gotcha's with inverting the axis in the manner?
I tried panning, zooming and using the CursorTool to retrieve the X,Y value information (cursortool line is configured as vertical only), being derived from this seems accurate.
Regards,
Ben.

No, not that I know of. If there is a problem, then it should be fixed. Do please let me know if you come across something you don't see as correct.
