[paida-users] Re: bug in DataPointSet?

[<dm...@bl...>]

Hi

Sorry for my late response.

I tried the fixes in 3.2.1_2.2.1 and now it reads in and plots my 2D datapointsets
properly. Thanks a lot for the quick fix.

However I found two new issues:

(1) if I open an xml file with the dtd definition in the header, i.e. something
like 
<!DOCTYPE aida SYSTEM "http://aida.freehep.org/schemas/3.0/aida.dtd" >
it crashes if you don't have a web connection. If you are online, everything
is fine. If you remove the line, everything is fine, too. I don't know whether
this behaviour is a feature or whether it's the fault of some xml module.
But it would be reasonable to ignore this line if no connection can be made.
See for the output further down.

(2) plotting an overlay of two different DataPointSets in the same region
doesn't work (options: scatter and with error bars). Plotting them separately
in different regions works fine. The error happens when calling region.plot()
for the second time. Here again, I have no idea what is going on so I also
append the output.

Thanks for help
Alex
