Hi,

I am trying to plot two arrays of data using TGraph. I seem to get a
segmentation fault when using the constructor, but dont understand why.
I just did,

TGraph *gr1 = new TGraph(size, tau_mom_t, cos_theta_t);

size is an integer, and the latter two arrays are arrays of doubles.

The complete error message is:

*** Break *** segmentation violation
Root > Function pvstheta() busy flag cleared

pvstheta is my function that I created.

Someone posted a reply to a similar question before but I didnt understand
the answer.

Thanks for your help,

Mark.
