Hi.

Yes, sure this is possible. If you're using ColorBand tool then you can read it's StartValue and EndValue properties. If you're using two color line tools, then you can read individual tool Value property.

Hi. I've tried your exact code with the TeeChart v7.08 and it worked just fine i.e. unchecking/checking the "3D" checkbox switched between 2d and 3d pie. Which TeeChart version are you using ? Do you try to add series at design time or at runtime ? If first, then perhaps you should remove/rebuild yo...

Hi. You might try the following things: 1) Decrease the separation between labels. This can be done by setting bottom axis LabelsSeparation property to small value (for example 2): tChart1.Axes.Bottom.LabelsSeparation := 2; 2) Another thing you might try is rotate axis labels 90deg anti-clockwise to...

Hi.

Is this the complete source for custom series ? You're actually using "normal" pie series with customized series editor ?

Hi. If you want to show the tChart print preview form, then you can do this by: I) a) dropping a TChartPreviewer component on the form b) connecting the TChartPreviewer component with chart you want to preview. This is done by setting TChartPreviewer.Chart property: chartPreviewer1.Chart := Chart1; ...

Hi.

Yes, this can be done (by using a TPieTool tool). In TeeChart demo, please check the "All Features -> Tools -> Pie Focus" node. It moreless does exactly what you need.

Hi.

No, not by using SetMinMax method. But you can use the following code:

Code: Select all

  With Chart1.Axes.Left do
  begin
    AutomaticMaximum := True;
    AutomaticMinimum := False;
    Minimum := 0.0;
  end;

Hi. You could use point series OnGetPointerStyle event to change individual point pointer style. Something like this: function TForm1.Series1GetPointerStyle(Sender: TChartSeries; ValueIndex: Integer): TSeriesPointerStyle; begin if Sender.MandatoryValueList[ValueIndex]>22 then result := psDiagCross e...

Hi.

If you're using multiple series then the solution to your problem might be setting chart Legend.LegendStyle property to lsSeries:

Code: Select all

Chart1.Legend.LegendStyle := lsSeries;

Hi.

If you simply want to remove/free all series in the Form::OnClose event, then all you must do is cal the

Code: Select all

tChart.FreeAllSeries(nil); 
To remove&free specific series you can use:

Code: Select all

tmp := tChart.Series[0];
tmp.ParentChart := nil;
tmp.Free;

Hi. SeriesExists function has to be coded (doesn't exists). The idea is to cycle through all chart series and if there is a match (series title is equal to "Well" column name, return series, otherwise return nil.). It's not too complicated at all: function SeriesExists(aChart: TCustomChart; ColName:...

Hi.

How did you create and connect linetool to chart ? The following code works just fine:

Code: Select all

var line: TColorLineTool;
begin
  line := TColorLineTool.Create(Chart1);
  Chart1.Tools.Add(line);
  line.Value := 0;
  line.Axis := Chart1.Axes.Bottom;
