Re: TColorGrid - Palette/Color Range Difference

Hello Yeray, thank you for your help. Why 2 switches UsePalette and UseColorRange? Can I use both together. I thought one excludes the other. This was probably to keep backwards compatibility. But as you've noticed, the Palette and the ColorRange can't be used together. Oh, now I understand it. The ...

Re: To raw point size increment

Hi Andreas, So I miss the feature to draw f.e. a 6x6 rect-point (only with border). I can draw 6x6 transparent pointers like this: uses Series; procedure TForm1.FormCreate(Sender: TObject); var Series1: TPointSeries; begin Series1:=TPointSeries.Create(Self); Series1.FillSampleValues; Series1.Pointe...

Re: Bug TColorgird TAnnotation Combination

Hi Narcís, thank you for the answer. Indeed your code works. The code Series1->IrregularGrid=false; was the problem. As I see the TColorgrid works in general not in inregular grid mode with negative values (althought the values are filled regular means äquidistant). The colorfields are show only in ...

Re: Circle shape center at invalid position

Thank you for the help.
I uploaded the files again.

I made "hardcopys" of some chart areas with a lense tools.
Maybe you can take a look on it and find out if its is a vcl-problem.
The circle_move_error.bmp shows a point at coordinate (0,0), but it doesnt look so.

Bye

Re: Circle shape center at invalid position

I had uploaded the files with the webinterface - The "upload attachment" tabpage.
But I do not really understand this function.
Are the files connected to the current discussion thread and where one can find them?

I uploaded it again at your upload page, now!

Re: Circle shape center at invalid position

Hello Yeray ! Yes, I use code like this. The example I tried to show in the ASCII-Fomat I cannot reproduce. (May be I had linewidth 2, then I get such results) In the 3 attached examples you can see 2 asymmetic circles and one at the coordinates (0,0). Here you see the x/y grid of the chart, at red ...

Hi Andreas, I've seen that this works fine with v8 so I'm afraid that you should downgrade to the last v7 that works fine for you or upgrade to v8. Unfortunatel I have no setup of the old version for 2007. It is a complete other setup. Where can I get it? But I guess it has to do with the 2007 vers...
