Hello,

we are using TLineSeries in a situation where we decide after the creation of the series if the line should be visible or not.
Until the last build we were able to hide the line by setting Series->LinePen->Visible = false.
Now this setting does not have an affect any more (only the symbol in the legend becomes larger).

Is this a bug or desired behavior?

Thanks in advance for an answer,

regards

Hans

Hello Narcís,

Thanks Hans, confirmed!

Hello Hans,

Also, as a workaround, you can disable series at Chart -> Series or at run-time setting the Active or Visible properties to false:

Code: Select all

  Series1.Active:=False;

I'm sorry, this won't work because I want to hide the line only, the points should still be visible. It's like switching from TLineSeries to TPointSeries.

Hello Hans,

This has just been fixed. I sent you the unit with the fix.

Hi, this seems to be a problem in Delphi 10.1 Berlin, update 2 - TeeChart Pro VCL FMX 2016.19.

Updating (very) old code, and setting LinePen.Visible to False, makes no difference, temporarily I can use .Active - but not as a permanent method.

Hello,

As you can see in the comments #486:

Is this your situation?
Why can't you use Active property at long term?
