Hello guzial, Ensure that you have set the following properties to true: YourLineSeries.ColorEachLine:=true; YourLineSeries.ColorEachPoint:=true; If this doesn't help, could you please send us a simple example project we can run "as-is" to reproduce the problem here? You can post your files at news:...

Hello Kev, the following example shows you two ways to achieve it: procedure TForm1.ChartTool1DragLine(Sender: TColorLineTool); var x, y, index: Integer; begin x:=Series1.CalcXPosValue(ChartTool1.Value); //first way for y:=Chart1.Axes.Left.IStartPos to Chart1.Axes.Left.IEndPos do if Series1.Clicked(...

Hello drueter,
You can use OnClick event as follows:

Code: Select all

procedure TForm1.Series1Click(Sender: TChartSeries; ValueIndex: Integer;
  Button: TMouseButton; Shift: TShiftState; X, Y: Integer);
begin
  Chart1.Title.Caption := 'Clicked Pie: ' + inttostr(Series1.CalcClickedPie(X,Y));
end;

Hi rhyden, you're right, this is a known issue in our wish-list to be enhanced for future releases. In the meantime, In order to do what you need, you can do something like the example bellow: unit Unit1; interface uses Windows, Messages, SysUtils, Variants, Classes, Graphics, Controls, Forms, Dialo...

Hello mh, To plot an area series you should have, at least, two points to define a valid area to be plotted. Anyway, if you wish to achieve what you request you could use something like the AddValue method and OnGetPointerStyle event (to show the points you need) as in the example we implemented bel...

In the following example, we made two series in two different charts, we set different legend widthes and aligned them. procedure TForm1.FormCreate(Sender: TObject); begin Series1.FillSampleValues(100); Series2.FillSampleValues(200); //Creating diferent size titles for each legend Chart1.Legend.Titl...

In the following project I added in design time: -bar series -edit box and updown button relationed and inicialized to 12. This is only to see and change the right margin. You can consider it optional. procedure TForm1.FormCreate(Sender: TObject); begin //Adding some data to the bar series Series1.A...

Hi Pete, We ran the following code without being able to reproduce your problem: void __fastcall TForm1::FormCreate(TObject *Sender) { Chart1->View3D = False; for (int i = 0; i < 500; i++) Series1->AddXY(Now()+(0.01*i),random(100),"",clRed); Series1->XValues->DateTime = True; } void __fastcall TForm...

Excuse us, you're right. This property has been added at version 8 beta and thats what confused us because it's the one we're working in. If you're interested on beta testing v8 let us know and we will provide you the necessary information.

Hi ellab_user,
You should do something like following:

Code: Select all

TChart1.Tools.Items(0).asAnnotation.Callout.Brush.color = vbRed

Hi Thomas,
You can take a look at this post

Hi Daniel, probably not all your XValues for RealTime have a corresponding XValue in PredicatedLine. So you'll probably need to compare for each XValue if it has a corresponding XValue in PredicatedLine. But then there are two possibilities: -Assuming for all XValues, if they have an image, they are...

Hi nileiqi, if we undestand your problem it should be solved using locate function, something like following: procedure TForm1.FormCreate(Sender: TObject); begin PredicatedLine.FillSampleValues(100); PredicatedLine.XValues.DateTime := True; end; procedure TForm1.Timer1Timer(Sender: TObject); var ind...

Hi nileiqi, If your real-time line and your predicated line share the same X values then your problem could be solved with some like following: (Note that we added 3 series and a timer to the form in design time and also note that we calculate residual points by subtraction of RealTime from Predicat...

Hi amih,

Using TeeChart v7.07 the next line of code works fine for us:

Code: Select all

TeePreviewPanel1->Margins->Visible = false;

If it still doesn't solve your problem, tell us what version are you using and we'll look for another solutions.
