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 ...

Hello ! I do not really understand the difference between Palette and ColorRange and how do the work. First of all: Why 2 switches UsePalette and UseColorRange? Can I use both together. I thought one excludes the other. The formular for color calculation of the palette I found: Procedure TSurfaceSer...

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...

Hello I use TChart V7.12 Vcl. I use scatter plots with a lot of points. I want to optimize the the points size so that I get beauty plots. Unfortunately in TeeChart I must configure the point radius and not the diameter. So I get for a RectShape without border the sizes: 2x2 4x4 6x6 8x8 etc. I miss ...

Hello ! I use TeeChartPro 7 Vcl. First I began with TColorGridSeries and figured out how to configure custom Palette-Levels. This workes fine. Now I want to adapt this feature to contour-series. I want to reconfigure its Levels (Isoline numbers). In the TeeChartPro demo I found following code proced...

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 ...

Hello I use TChart V7 vor VCL and test the TColorgrid for the first time. I found the following bugs. 1. Grildline are cutted for negative values x -10 10 y -10 10 For negative x and y you see no gird lines for negative x only vertical lines are drawn for negative y only horizontal lines are drawn 2...

Thank you for the answer.
The result looks perfect for me - that is what I expected.
Ok I will update.

Hello ! I use TChart 7.12 VCL. You can produce the error with the TChart-Editor: Insert a TBarseries fill it with 3 samples. The x-Points are: 0. Bar -0.5 .. 0.5 1.Bar 0.5 .. 1.5 3. Bar 1.5 .. 2.5 Thats ok, but when you widen the x-Axis range maybe to -3 .. 10 the bar have different width and positi...

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
Andreas

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!

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 ...

Hello ! I use TChart 7.12 and have have problems with a TLineseries, if I set its SeriesPointer->Style = psCircle. HorizSize and VertSize to the same so that I should get circles. 1. For small sizes 3-7 the cicle shapes does not look very beautifull as a circle Should the shape not be symmetic in x ...

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...
