Hello

I replaced my embarcadero tee version with the standard version1.14 a few days ago.

I installed it and yesterday I recompile a project with about 10 TCharts and a lot of TLineSeries(maybe 30 or 40) and 1 TBarSeries
All series receive date via tcp and have to show them immediately.
The timer intervall is 1000ms
There are no timing problem with the old tee componnents.

But the new one needs about 15 sec(!!!) to initinalize the charts and Series at app start. Windows said "app not responding".
Then it works , but from time to time , my app hangs and Win comes again with "appl not responding".

So I recompile the procect on another computer with the old tee components, and all works fast as it should.

Has anyone an idea , whats going wrong ?
Is it a problem between CBuilder 10 and new Tee components , is the compiler too old ?
Is it an installing problem ?

Thanks in advance
Jörg

I'm not sure to understand what version did you install.
https://www.steema.com/version_info/vcl

Regarding the performance in general, find here some tips to improve the performance when drawing many points. The majority are related to the TFastLineSeries, but some of them are more general.

Also note you may want to disable Hover feature if it's enabled.

If you still find problems with it, please arrange a simple example project we can run as-is to reproduce the problem here.

thanks for your replay

I used a long time the teeChart Version comes with the Emarcadero CBuilder-
Is called
TeeChart Standard v2016.17.160129 32Bit VCL.

All in all, the components work fine, but the was some silly things like A Line was mot cleared, some color errors and so on.
So I make an update to the new version to the new standard version1.14 a few days ago.

And I recompile the project with the new version and it's very very slow , so I deinstalled the new TeeChart and use the old components , recomile and it runs normaly.

Is the comiler too old ?
"Hover" is disabled , and was disabled by using the old version.

I will read your tips, thank you again, and then I will try to install the new version again.

Hello

You mention "version1.14" again, but I'm afraid I'm not sure to understand what version do you mean.
If you look at the release notes, there's no version 1.14 for TeeChart.

Good. If you still find problems with it, please clarify what TeeChart version are you trying to install.

I buy the "standard vcl licence"

Order Number....: w202311127
Date............: November 29, 2023
Total...........: 99.00€ + VAT

And I get the Install exe named "TeeChartVCLFMXStandard-2023.39.exe"
I guess thats the newest version of TeeChart for VCL .

Thanks and merry xmas

Thanks for confirming the version you are trying to use.
If you still find problems with it after trying those tips to improve the performance, could you please arrange a simple example project we can run as-is to reproduce the performance drop you are observing between TeeChart v2016.17 and TeeChart v2023.39?

Thanks in advance and merry xmas to you!

yes ok

if I find something , I contact you.

Thanks
Jörg
