Hi guzial,

you can try doing something like this:

Chart1.ExchangeSeries(Series1,Series2);

Hi amadeus, The code bellow shows you an example of how you can change the labeltext using OnGetAxisLabel event: Private Sub TChart1_OnGetAxisLabel(ByVal Axis As Long, ByVal SeriesIndex As Long, ByVal ValueIndex As Long, LabelText As String) If Axis = 3 Then LabelText = "Q" & CStr(CInt(LabelText) + ...

Hi guzial,

Yes, this is a known limitation. Existing PDF export filter does not support transparency (missing pdf implementation). We have this on our wish list for next major TeeChart release. In the meantime the workaround is to disable (set it to 0) the transparency.

Hi Richard,

You should use something as following:

Code: Select all

ChartListBox1.ClearItems;
ChartListBox1.AddItem('Series3',Series3);
ChartListBox1.AddItem('Series4',Series4);
ChartListBox1.AddItem('Series5',Series5);

Hi guzial, Following the steps in the article above I've made an example with 6 series and 1000000 points in each one and it takes about 8 seconds to draw the chart in my machine. The code I use is: unit Unit1; interface uses Windows, Messages, SysUtils, Variants, Classes, Graphics, Controls, Forms,...

Hi guzial,

you can take a look at this article to optimize your LineSeries.

And also note that we've added it to our wish list to be considered for further releases.

Hi guzial,

you can solve this issue assigning a series to the cursor tool.

Hi guzial,

We're sorry but you should use TLineSeries to achieve ColorEachPoint to work properly.

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...
