New profiling module for wxgrass

[Michael Barton]

Some javascript/style in this post has been disabled (why?)

Following up on the general gist of discussions about graphing, I created a new profiling module for wxgrass using the plot module in wxPython. Although the docs stated that it required numeric, numarray, or numpy as a dependency, it was not clear during development if this particular application of the plot module did indeed require this.

I’ve now tested it on another system and can verify that to run the new profile module (profile.py) you’ll need one of these dependent modules (any will work). They are available from a variety of sources. I’ll try to get together a list and put it in the README if we want to continue with this.

I will say that doing the profile with plot produced a very nice result (I’ve attached a screenshot here) with about 1/3  of the code I’d need to do it manually. It also makes it very easy to do other simple graphs (mainly line and point graphs, though bar graphs are also possible) with very little in the way of coding—built in save to file, printing, zooming, dragging, scrolling, and log scales for example.

Let me know what you think (after you’ve installed numeric/numarray/numpy).

Michael

Hi Michael,

it looks nice, but it does not seem to work for me. When I draw the
profile and click on the "create profile" button, I get:

  File "/usr/src/gis/grass/addons/gui/gui_modules/profile.py", line 320,
in CreateProfile
    self.pline = plot.PolyLine(self.datalist, colour='blue', width=2,
legend='Profile')
  File
"/usr/lib/python2.5/site-packages/wx-2.8-gtk2-unicode/wx/lib/plot.py",
line 224, in __init__
    PolyPoints.__init__(self, points, attr)
  File
"/usr/lib/python2.5/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

Thanks for this effort

Jachym

Do you have numeric, numarray, or numpy installed (and the proper one for
your Python version)? Also, does the Pyplot demo work for you?

hi,

I had to install all tree packages - now it works.

Great work!

I wonder if it really needs numpy and that the other two are too old, in
spite of what the docs say?

python-numpy - needed for profiling tool
python-numeric - several gnome and other packages are using it
python-numarray - not needed

Each segment is marked with a point (default a triangle, but you can change
that). I'd originally marked the beginning and ending of the transect with a
point too, but Hamish suggested that it looks better to exclude these.

Glad this is working for you.
