Displaying a range on the chart

Hello
I'm trying to display on the chart a range between high and low limits.
I want it to be half transparent (like a peice of Cellophane on the chart).

Does anyone know how can I do it?

Thanks, Libby

Hi Libby,

Yes, you can do this using a SeriesBand tool. You should use two line series and then make its pen invisible as shown here:

Code: Select all

procedure TForm1.FormCreate(Sender: TObject);
begin
  Series1.FillSampleValues(10);
  Series2.FillSampleValues(10);

  Series1.Pen.Visible:=false;
  Series2.Pen.Visible:=false;

  ChartTool1.Transparency:=50;
end;

For more information on how to use TeeChar tools please have a look at the tutorials, available at TeeChart documentation or at the TeeChart features demo, available at TeeChart program group.

Hi
Can you please add an explanation how to add the ChartTool1 to the chart?
In the list of tools I have a "ColorBand" not a "SeriesBand". Is it the same thing?
Can you direct me to a specific demo that I can run or a specific tutorial?

Hi Libby,

You'll find examples on how to use TeeChart tools at the TeeChart features demo available at TeeChart program group. However you can easily add tools to your chart just double-clicking on it, openning Tools tab, clicking add and select the tool you want to use.

In the list of tools I have a "ColorBand" not a "SeriesBand". Is it the same thing?

No, which TeeChart version are you using? SeriesBand tool is available at TeeChart Pro v7.

Can you direct me to a specific demo that I can run or a specific tutorial?

I'm afraid there's no specific demo for SeriesBand tool.

OK, Thanks.
I guess I'll have to upgrade.
