#30 Calling drawLineGraph with XY pData will loop forever

[Matthias Grimm]

Hi,
Calling drawLineGraph() and relatives with a pData structure set-up for a XY graph, will loop forever with CPU=100% (until the PHP compiler stop the process).

I haven't digged too far into this problem but a validity test with warning message or skipping the series marked as X should fix the problem.

Best Regards
Matthias
