[fixed] Access violation with DataPointMarksClickTool

[Muso]

I use the new DataPointMarksClickTool and encounter an access violation:
* take the attached example
* run the program in debug mode and Shift-left-click into the chart on a position where no data is
result: ACCESS VIOLATION in this line of TACustomSeries.pas:

Code: Pascal  [Select][+][-]

1. lfont.Assign(Marks.LabelFont);

I could not yet find out why this happens because I use the default font settings.

Lazarus 2.3.0 (rev main-2_3-2941-g84f716a2ff)
FPC 3.2.2
x86_64-win64-win32/win64

Cannot reproduce, no exception.

Shift-left-click into the chart on a position where no data is

Are you sure that this description is correct? The MarksClickTool has ssCtrl in Shift, rather than ssShift. There are no data anywhere, there is only a ConstantLine series. So why do you emphasize the "no data"? Is this sentence simply copied from the other post?

Sorry, yes I meant Ctrl+Leftclick.
With empty I meant, don't click on the line.
Attached is a screencast of the access violation.

Still cannot reproduce it. Could be that the previous commit for the other post fixes this too. Please check and report back.
