[Visualpython-users] ghistogram

I have been running into some problems with the ghistogram routine.  I have 
some data, which includes negative and positive values.  When I set the bins 
and xmin, xmax to allow for this, the distribution ends up piled up on the 
xmax side of the plot.  If I offset the data to be just positive, it works, 
but the plot is not as clear.  Did I miss something and this feature only 
allows for positive values?
