Thank you Yeray, It works fine for me too. At least, compiling and running the simple testRectangleXE2.zip. Now, I can also compile my own Tee Tools but I can't assure that it works or crashes at running time because I'm still correcting other running time errors starting the big application using t...

Hi, I need to reopen this thread because the problem is still alive. I've been working the last few days importing from C++ Builder 2007 to Builder XE7. After struggling a lot of compile and link problems, I'm halted on this one. Here's again: [ilink32 Error] Error: Unresolved external '__fastcall V...

Hi Yeray, I got this too. You just may derive from TLineSeries and override the DrawValue method like this: void __fastcall TISALineSeries::DrawValue(int ValueIndex) { x=GetHorizAxis->CalcXPosValue(XValues->Value[ValueIndex]); // x coordinate for ValueIndex y=GetVertAxis->CalcYPosValue(YValues->Valu...

Hi, I've been working in speed improvement with TPointerSeries and now I can work with several million points 10-15 times faster. To do so, I've implemented my own class derived from TPointerSeries and reimplemented 2 functions only, but the most important thing I did is preprocessing to choose whic...

Hi Yeray, thanks anyway, the important thing is there's no bug anymore, in spite of losing speed while zooming. I'll get a more powerful PC so far, but you should consider to improve this kind of speed issues in series with Pointer (TLineSeries, TPointSeries). Besides, I suggest another way to manag...

Hi Yeray, yes, I can see speed differences in that application but maybe your computer is quite better than mine, so you have to use more points. You can change the line: LoadChartFromFile((TCustomChart*)Chart1, "chart.tee"); for this code: TPointSeries* series = new TPointSeries(Chart1); Chart1->Ad...

Hi Yeray! Yes, I follow the tips of your real-time charting article since several years ago and they are a great improvement. Anyway, there's a huge speed difference between AddXY and DynamicArray in spite of disabling AutoRepaint (or the Series->BeginUpdate thing). The good news is that the zoom bu...

Hi, I have this bug since forever but now I can reproduce it for you. I have this issue almost every time I zoom all kind of charts I have with one TPointSeries in them (no more series), and It turns out that if I add points with AddXY instead of using DynamicArrays, this issue is not present. The b...

Hi, If you were upgrading from an old version (or downgrading from a newer one) that seems to be a mix of different TeeChart versions while compiling, linking and running. I would rename older version folder, check the TeeChart packages used in your projects and rebuild all the way. Hope you get it ...

Hi, I uploaded two images for you to see how I currently see 4 of my graphs and how I see them using TeeOpenGL. As you may see, 2D series are not shown using TeeOpenGL, so I can't tell differences. Anyways, I'm trying to enhance my source code and I have one question: How could I know the drawn poin...

Hi,

I saw your screenshots and the appearance are similiar to mine (texts are blury, for example), although 2D view does paint the series. So, isn't it possible to get the same looking for charts than without using TeeOpenGL?

Thanks.

Hi Yeray, I tried your exe file and I compiled your changes myself, and the result is in the screenshots attached. As you may see, 2D series doesn't appear and the looking is really hideous in both views :lol: I also tried in another computer using the same runtime packages of TeeChart (Tee711.bpl, ...

Hi Narcis, It's been a while that I'm using TeeChart Pro v7.12 Win32 and CodeGear™ C++Builder® 2007. You are referring to TeeOpenGL, aren't you? If so, check the attached zip file. It includes the Builder project, the executable file renamed to have .axe extension (TeeOpenGLTest.axe in the Debug fol...

Hi,

The DownSampling is not suitable for my charts because I use several own chart tools to identify and match points between several different charts (altough representing the same data).
The TTeeOpenGL doesn't seem to work in 2D charts, only 3D (and It works really weird).

Thanks.

I forgot to mention that almost all charts I need to improve are 2D.

Thanks!
