You need to use the 'imshow' function to display an image in greyscale. You
have to turn your image into an array of values and then put that array
into imshow with the colormap set to grey.
I don't know about how to do a plane fit...

Thanks Alexa and Jerzy.
other questions? ... Here they are:
- changing to an image grey scale only needs ... what?
- I need to do a 'plane fit' of the image. Does matplotlib
have some routine for this? Or shall I use other math libs?
Thanks again.

This *alone* will not do, the image might be scaled badly. Add extent.
Try this:
fig = plt.figure()
frame = plt.subplot(111)
im=frame.im
Try using 'xticks' and 'yticks', those commands let you define the location
and label fo your tick marks.
Example -
xticks( arange(5), ('0', '100', '200', '300', '400') )
Where the argument in arange is the number of tick labels you're making

Hello,
I don't know if I can ask questions concerning matplotlib problems
in this email list ... just let me know that this is not the right
place, if.
I have an image, which I can read and put into a figure. The image
has axis and I can even save the image. I have two issues:
1. Since it is an

Hi Everybody,
I'm trying to label the contours of my contour plot following this example

I have some figures with multiple axes stacked on top of each other,
generated with Figure.add_subplot(). In each figure, some sets of these
axes are logically grouped together, and I need some visual clue of which
axes are more closely related.
The right way is probably to use GridSpec [
