Teechart - Lines

jufloren

Hello everybody!

I'm developing a report with chart. I need to change the "line > title" and "active" properties in run time, but when I use the command below I receive an error message:

Chart1.Series(0).Active := False;
Chart1.Series(0).Title := 'my title';

"Project xxx.exe raised exception class Exception with message 'Index required'."

Honestly, I can't find any help about this issue. I'm still researching about this issue at the Internet, but it is a hard work.

Thanks a lot.

To change the property "active", I executed the command below:

Chart1.Series[0].Active := False/True;

Now, to change the series title, I have no ideia how to do it (yet).

Hello gordk...

This command didn't work, I've tried this before. The "Title" property doesn't appear when I press CTRL + SPACE in FR IDE, after "Chart1.Series[0]." command. When I try to run the report, an error message occurs:

"Project ..... raised excpetion class EVariantTypeCastError with message 'Could not convert variant of type (Null) into type (Null)."

Thanks.

TBarSeries(Chart1.Series[0]).Title := 'test';
