Delphi 7, TCharts 8.02 and TChartGrid

Solar · Post by **Solar** » Wed Jun 04, 2008 8:56 am

Hi,

I've been struggling with the ChartGrid for some time now:

As soon as I have more than one series in a Chart (connected to ChartGrid) everything is fine, but when I have only ONE series in a Chart (that is connected to the chartgrid), I only see one row of values.

I've tried leaving the "Series" property of ChartGrid blank, and filling it in (during runtime) with my series, but precisely the same thing happens. I only see one row. As soon as I add another series, I can now see both series's data, and all (100+) rows of data are displayed.

Is there some property I'm missing?

Thanks,
Christiaan

Hi Christiaan,

I'm not able to reproduce the issue here. Could you please send us a simple example project we can run "as-is" to reproduce the problem here?

You can either post your files at news://www.steema.net/steema.public.attachments newsgroup or at our upload page.

Thanks in advance.

Hi,

I just uploaded the file. It's a Delphi 7 project, just run it, and click on the button to do the graph. I have to randomly doubleclick on the ChartGrid for it to display all the values in the graph.

Please let me know if you can reproduce the problem...

Regards,
Christiaan

Hi Christiaan,

Thanks for the example project. Yes, we could reproduce the issue here, this is a bug (TV52013116) that we have added to the list to be fixed for next releases.

In the meantime, as a workaround, you can add line below after populating your series. This will refresh the grid.

Code: Select all

 ChartGrid1.Chart := Chart1;
