This problem is already fixed (InternalCanvas.Free), and will be included in next update. btw: If you apply the changes at "...\TeeChart Sources\VCL" folder, changes are lost because TeeRecompile tool recreates this folder. The "original" source unit that can be modified are one level up, at "..\Tee...

Another solution that might work without modifying TlineSeries source code is:

Code: Select all

procedure TMyLineSeries.DrawValue(ValueIndex:Integer);
begin
  FDrawLine:=DrawSegment[ValueIndex];
  inherited;
  FDrawLine:=True;
end;

Hi ! There's a new sub-project (the idea is to include it with the next future version of TeeChart), to perform "Clustering" algorithms. For more information and an executable beta example, visit this link: http://www.steema.us/files/public/teechart/vcl/demos/clustering/TeeChart%20Clustering%20tutor...

A workaround you can try is to add one unit to "uses" clause: uses OpenGL; This unit is already setting the 8087 fpu mask exclude-exception bits, at the unit initialization, so it might help solve the printing exception. (The Microsoft Windows OpenGL32.dll already "suffers" from masking floating exc...

Thanks, leak fixed in latest v8 beta sources.

These new events have been added in v8 beta. Chart1.OnAddSeries(Sender:TCustomChartSeries); Chart1.OnRemoveSeries(Sender:TCustomChartSeries); They are called just after a series has been added to a Chart, and just after it has been removed. Note: Adding or removing a series to a chart happens when t...

In VCL (Delphi) the syntax is: var i : Integer; i := Chart1.SeriesList.Count; In C++ Builder: int i ; i = Chart1->SeriesList->Count; Chart1.Series.Count cannot be done in VCL as "Series" is an indexed property: var s : TChartSeries ; s := Chart1.Series[123]; and indexed properties do not allow stand...

TeeChart Standard and TeeChart Pro v8 VCL beta has been released. Expected release date will be aproximately at the end of the year. There are quite many changes and additions in this new v8 version. We appreciate your help in providing us with feedback about the new features, bug fixing and ideas. ...

It is already included in the VCL version of TeeChart. See the TDBTree control and right-click it at design-time to show the database wizard dialog. TDBTree is part of TeeChart Pro and it is installed by default at "TeeTree" tab at Delphi / C++ Builder component palette. A compiled executable demo o...

Hi Steve
This I think can be done by using the gradient Middle color, and setting the StartColor to the same color as EndColor. This works both in horiz and vertical directions.

The "InternalUse" trick is now obsolete and no longer internal. There is now a public boolean property that controls if a Series or Tool should be displayed at runtime at the editor dialog. ChartTool1.ShowInEditor := False; This property can be changed at design-time using the same TeeChart editor a...

In Delphi (VCL) you can control this using the Application class: Application.HintHidePause:=8000; // <-- show the tip 8 seconds I've added a new property to MarksTip tool that links to it. ChartTool1.HideDelay:=5000; // 5 seconds The default VCL time amount is 2500 milliseconds. Note: When changing...
