Hi! I would like to know about all options I have to enhance drawing speed. I already use all recommendations in your "Real-time charting in TeeChart VCL" article since several years ago, but yet I'm trying to improve speed with other complementary ways. Besides, some of my charts have to use other ...

Thanks Yeray. My workaround is similar to yours, but both are not good at all . :lol: Your code has several problems: 1) Margin offset is calculated based on labels, but axes can have its title. 2) Changing MarginUnits affects to all default axes (no problem if using muPixels from the beginning) 3) ...

I forgot earlier... there's no need to hide the LeftAxis, the same issue appears if labels custom axis width is quite wider than the LeftAxis's.

Thanks!!

Hi, I thought you would know what I'm talking about :) When using custom axes (at least with vertical axes), if you hide LeftAxis, the positioning of all vertical custom axes is not good; probably you won't see their labels completely. It seems that the positioning of all customAxes depends of the p...

Hi,

I have lived several years with the weird behaviour of vertical custom axes positioning when LeftAxis is hidden. The last version I tried is 7.12. I would like to know if this issue is fixed in later versions. If not, ¿there's any workaround you recommend me?

Thanks in advance!

Hi Narcís, I'm glad you could reproduce this issue. It appears with Builder 2006 too (and TeeChart Pro 8.0x). I'm gonna have to keep on using TeeChart 7 until you find a solution, because I have several classes inherited from TAnnotationTool and It would be to much work to do if I take your alternat...

Hi Narcís,

I've just uploaded a .rar file with the project.

Thanks.

Hi, (I'm using Borland Depeloper Studio 2006) I recover this old post because I was trying to upgrade from TeeChart7.07 to TeeChart 8 AGAIN. Last time I got TeeChart 8.01 evaluation version and one linker error showed up: [Linker Error] Error: Unresolved external '__fastcall Teetools::TAnnotationToo...

Hi, I installed TeeChart 7.12 and got lot of linker errors of .obj files missing. I checked installation folder /lib/obj and there's only 22 .obj files instead of more than 200 in 7.07 version (my previous installation). I didn't get any install error. ¿Would you tell me if there's only 22 .obj file...

Hi Narcís,

That is exactly what I needed to calculate positions of some chart tools I have made.
Thank you very much.

Beetle.

Hi, I need a way to know the exact position of the begin and end of one TChartAxis. In the case of the BottomAxis, It is not always possible to get it from this sentence: int xBegin = chart->BottomAxis->CalcPosValue(chart->BottomAxis->Minimum) because there are cases in which that would be incorrect...

Hi Pep, I've just installed TeeChart 8.01 again and I didn't get any error during installation. I believe that all components are in the TeeChart palette. I can drop a TChart component on one form, compile and execute that project (and "play" with a TChartEditor). BUT I can't create any object of a ...

Hi Pep, I was trying to install the TeeChart v8.01 trial again to reproduce that linking error, but I got the same error all the time, over 100% installation progress: TeeChart Installation VERSION: 8 D2006.Win32 v10 (update 2, HotFix: 9) (BDS v4 Architect) (C++) EXCEPTION: Invalid filename --------...

Hi,

Yes, that's the evaluation version I had tried, so the one with the problem.
did you try my test?

Thanks.
Marcos.

Hi,

I'm afraid my current license is not valid anymore (just for TeeChart 7).
That's why I was testing the TeeChart8 evaluation version.
Any newer evaluation version?

Thanks.
Marcos.
