I am new to ChartPro. I want to change x and y axis range of one graph.

I use the following code:

CXTPChartAxisRange* pRange = pAxisY->GetRange();pRange->SetViewAutoRange(FALSE); pRange->SetViewMinValue(dYmin);pRange->SetViewMaxValue(dYmax);

similiarly to X axis. But I didnot get what I want to restrict x axis between dXmin and dXmax, and restrict y axis between dYmin and dYmax. Is there anything I should change?

Thanks!

you need SetAutoRange(FALSE), GetMinValue/GetMaxValue instead.

I think you mean SetAutoRange(FALSE), SetMinValue/SetMaxValue right? definitely not get. I tried that, it is not working. It changes my y axis to between dYmin and dYmax, but didn't change x axis to between dXmin and dXmax.

Another question is how I can control the numbers shown under the axis. For example, the x axis range is from 1 to 10. I want it show like 2,4,6,8,10. How can I control that?

find the solution.

Oleg, I think the problem for my question is solved. I added the following, then it works fine. Thank you!

pSeries->SetArgumentScaleType(xtpChartScaleNumerical);

I'm very sorry to say, but I'm totally lost specifying the axis range? And no documentation?

What is the difference between SetViewAutoRange and SetAutoRange for an axis?
Why has SetMinValue and SetMaxValue no effect at all?
Should I also set SetViewMinValue and SetViewMaxValue?
Can I change between different ranges after adding data?
Sometimes I get a small scrollbar on the graph, how do I control that?

Ok, now I just figured out that auto range has no effect on CXTPChartFastLineSeriesStyle. Probably make sense, but an assertion would have been in place.

On the other hand I cannot turn antialiasing off for CXTPChartScatterLineSeriesStyle.
