hello,
here is a very basic problem; I want to plot y=cos(x) with x from -PI toPI and so y from -1 to 1
I must be stupid as I didn't find the way to do this !!!!!
I can only plot y with numbers on the X scale, not the real values of X. I want to see floating numbers on the X axis, like "3.12" or "0.9".
Is there some sample code to demonstrate this ?
I didn't find anything in the manual.
From many years I used the TCharts vcl. It was very easy to plot XY series.
thanks for help
Dear Mr. Verwaerde,
We have uploaded a sample that demonstrates how this can be achieved.
Kind Regards,
Pieter
Thanks for the demo code, which works well.
I get 2 axis scales, the one up with counts, the second below with float values.
If I want to get rid of the count axis, the only way I found to do it, is to use the OnXAxisDrawValue function.
I have to point out that it's rather complicate to achieve a simple xy plotting if the x values are not counts or seconds.
This is the reason why I shall not use the advchart vcl for scientific data plotting.
Good job but not suitable for my application.
regards
I have same problem with 2 axis, would you share the solution. Uper one is x values inserted with addsingleXYpoint but lover just counts number of points 0,1,2,3....
Hi,
You can disable the lower values with AdvGDIPChartView1.Panes[0].Series[0].XAxis.XYValues := False;
Kind Regards,
Pieter
