Hello, I'm afraid there's no property to do this. However, you can do a trick. You can draw the series twice. - First, draw the series without BandPen the first time, and prepare a special palette with a single Level . - Secondly, draw the series without Brush and with a custom Palette which has a s...

Hello, I don't have EurekaLog here, but I've done a simple example creating a thousand forms containing a TChart with a TBarSeries and a TSelectorTool and, looking at the Task Manager while it does the job, the memory looks stable at about 2,9MB. SelectorToolMemory.zip Feel free to modify the exampl...

There will be an error message when compiling:
[dcc32 Fatal Error] UnitChart9Intraweb15.pas(7): F2613 Unit 'IWCompTeeChart' not found.

You need to add the folder where you uncompressed the zip to the "Library path" so the compiler can find the IWCompTeeChart unit.

Hello Peter, Indeed, the event is capturing the action and not propagating the event. If you want to change this behaviour, you can set CancelMouse property to False : procedure TForm1.Chart1ClickSeries(Sender: TCustomChart; Series: TChartSeries; ValueIndex: Integer; Button: TMouseButton; Shift: TSh...

Hello, The Pro packages would probably work for you but I've made new ones separated in 3 folders (Pro, Std, and StdCom) for more clarity. Note the "Std" packages are for TeeChart Standard/Lite shipped with the IDE, while the "StdCom" packages are for TeeChart Standard Commercial version. TeeChart 2...

Hello Willi,

Yes, you can change the Series' Selected.Hover.Pen properties. Ie:

Hello John,

I'm not sure to understand the situation. The shape series is clipped by default in the chartrect so the axes labels are always shown in a simple example for me here:

Hello,

Sorry for the delay here.
Find attached the packages for TeeChart v2022 for Intraweb 15 in RAD 11.

Hello, You could draw your million lines into a separate bitmap and draw it at Chart1BeforeDrawSeries : void __fastcall TForm3::Chart1BeforeDrawSeries(TObject *Sender) { //... if (backInvalid) { backChart = new TBitmap(); //backChart->Transparent = true; backChart->Canvas->Pen->Color = clGray; backC...

Hello, It seems like the "normal" way of finding loaded resources to free them causes memory leaks. This is probably a bug in RAD Studio so we implemented your workaround or using a variable. We also fixed the problem with the SeriesItems being loaded at design-time. I'll send you the latest modific...

Hello,

Drawing a million lines is always slow. That's why the majority of techniques we use to improve drawing performance involve reducing the number of lines to be drawn as you can see here.

Hello,

I've been able to reproduce the problem so I've added it to the public tracker (#2528).
Thanks for reporting it.

Hello,

Can you please send me a simple executable to run here?

Sure, find it here. I've tested it in a Win11 VM and it seems to work fine.

Hello,

Sorry for the delayed reply here.
The problem seems to be on the shadow drawing.
Could you please confirm if hiding it solves the problem for you?

Hello,

Sorry for the late reply here.
I've done a simple example project to test this and it seems to work without errors for me in RAD 11.1, both with the new and the classic compiler. Please, give it a try at the project above and let us know if it works fine for you.
