[GRASSGUI] wxgrass: histogram and profile

[Markus Neteler]

Hi

(thanks for the alphabetical order!). Another report:

# trying the histogram in LatLong, I get:

Traceback (most recent call last):
Traceback (most recent call last):
  File "/home/neteler/grassaddons/gui/gui_modules/histogram.py", line 374, in OnOptions
    menuform.GUI().parseCommand('d.histogram', gmpath,
AttributeError: GUI instance has no attribute 'parseCommand'

# trying profile on the same map
Traceback (most recent call last):
  File "/home/neteler/grassaddons/gui/gui_modules/profile.py", line 472, in CreateProfile
    self.DrawPlot()
  File "/home/neteler/grassaddons/gui/gui_modules/profile.py", line 492, in DrawPlot
    legend=' '+self.plegend1)
  File "/usr/lib/python2.4/site-packages/wx-2.8-gtk2-unicode/wx/lib/plot.py", line 224, in __init__
    PolyPoints.__init__(self, points, attr)
  File "/usr/lib/python2.4/site-packages/wx-2.8-gtk2-unicode/wx/lib/plot.py", line 124, in __init__
    self._points = _Numeric.array(points).astype(_Numeric.Float64)
ValueError: matrices are not aligned for copy
    

I get the profile error also on other maps.
Concerning the profile: It's not clear to me if I have to start with
the second icon from left. If so, it would be more intuitive to put
it to the left.

# concering distance measure:
I feel that the result in latlong is degree or so - could this be changed
to metric output (like d.measure does with G_begin_distance_calculations())?

thanks
Markus
