Yes you are correct. If I create the plot by opening the Log device and clicking on Create SVG plot - everything works perfect.
However I don't see any reason to do that if already have similar plot and just copy it under different name, change the plot file name, and change the field(s) I want to plot. Much more faster than making everything from scratch.
Will download the new module and will give you feedback.
Thank you for the fast reaction.
Just got the module from
https://svn.fhem.de/trac/browser/trunk/fhemThe output is (after restart, but the same on reload...):

./FHEM/98_SVG.pm has too many errors.
Edit: I reverted to the old version of the module, created the plot from Create SVG plot and finished what I wanted. However it is good to think for the above, since sometimes it is easier to copy or manually create the graphs. Thank you for the support. Will try of course the module after next update and will give you feedback.
