Re: Is TeeTree still maintained?

Hello,

TeeTree is shipped with TeeChart since years ago, that's why it doesn't appear as a separated product in the menu.
It's true that it hasn't received big updates recently but it doesn't mean it isn't maintained.
Feel free to ask here or post any bug you may find at bugzilla.

Re: Drawing a specific bandline on an IsoSurface plot

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...

Re: Exception with TSelectorTool and Eurekalog

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.

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.

Re: Map Series and Zoom

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...

Re: Use TeeChart in an IntraWeb application

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...

Re: Axis Labels Behind Shape Series?

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:

Re: Saving and re-using internal bitmap

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...

Re: FMX TChartListBox not working

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...

Re: Saving and re-using internal bitmap

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.
