setting size of the logviewer messes up the header section

[thoth291]

Here is what I did:

import petropy as ptr
log = ptr.log_data('WFMP')
# create LogViewer with 'raw' template
viewer = ptr.LogViewer(log,top = 6900, height= 2000)
viewer.fig.set_size_inches(11,30)
viewer.show() # diplay log data

And here is what I got:

As you can see GAMMA RAY is on top of GR - and etc...

Could you please help to debug this?
Thanks in Advance!
