Yeray, a simple example is to draw a chart with a TFastlineSeries. Simply add 50000 samples of Y-Value = 0 except sample 25000 = Y-Value = 1 and sample 25002 with Y-Value = -1 DrawAllPoints is ok but slow. Ok so far Now we select DrawAllPoints=false, but DrawAllPointsStyle =daMinMax So without zoomi...

I guess I made a wrong conclusion. The first picture show the high amplitudes. So the data points are there. But in the zoomed picture the high amplitudes disappear, despite DrawAllPointsStyle := daMinMax; So it seems that with DrawAllPoints switched off DrawAllPointsStyle is no longer in use and th...

Thanks for the information. Unfortunately it does not give all answers. My problem is that the chart must allow zooming. With DrawAllPoints:=false a series is quickly drawn. But then with zoom I get a wrong display. See an example with not too many points (justabout 65000 points): First the plot wit...

Hi, I like to draw a series with many points, e.g. > 5 million points. Of course as quick as possible. So TFastLineSeries is anyway the right choice. As the documentation lacks of details I wonder how to speed up the display but keeping the best visual information also with zooming. There are the pr...

Hello Narcís, as the displayed version number is not changed with different test versions it does not really make sense to talk about. Anyway the latest source has solved the exception problem. Furthermore I recognize that Delphi VCL is now running much quicker. Also the compiler benefits from speed...

Hi Yeray,

I use a source version which I have got by Narcís at March 13. It has solved other bugs
But I do not know if it has a different version number and where it is located.

Create a new project with TeeChart. Add a series. Select tab Gauges. Boom.
See picture
TeeChart 2014 Pro Source + XE4

Dear Narcís, I have tried to install the version you have sent but have simply failed. I have sent you also a private message about this. So right now I have re-installed the source of Feb. 24 again and switched back to GDI. It seems that GDI+ has some problems, see also TNumericGauge http://www.tee...

I have the same problem. So right now it only helps to switch the numeric gauge back to GDI rendering

Hello Narcís,

I do have the same problem.
It took me quite a while to detect for the reason why my exe code was growing and growing.

Can I get a bugfix as soon as possible please? I have to deliver my software.
I'm using VCL Pro source code 2014 with XE4

Thanks
Uli

With the new 2014 VCL Pro sourcecode version I get a wrong legend like this
Is there a solution for GDI+ ?
Switching to GDI gives a correct display.

Best regards
Uli (XE4)

Hello Yeray,

thanks.
I prefer to use your code example as I do not like the blurred GDI+ picture.

All the best (still wondering about the side effect of the legend shadow on BMP export)

Hello again, I like to come back to the problem. So I have created a small project that you can download by https://drive.google.com/file/d/0B8QsTWVB0IEhY3MzaE9zLTJaVm8/edit?usp=sharing The project contains the pas, dfm, dpr file as well as the exe file (renamed as exx). So you can run the program a...

Hello Yeray, it seems I have to dig a but deeper in my program. Creating your test example also works here (Delphi XE4, TeeChart pro v2013.11). But it does not work correctly in my application. So if I load two series at once both series are exported. If I load one series, export it and then add ano...

Hi,

exporting a chart in BMP format by the chart editor seems to fail. It only exports one series. The preview shows all series correctly. But saving is not ok.
