Also are there anything I need to do to make MacOSX available to matplotlib. I have installed XCode, but I notice that there is no longer a /Developer directory at the root level (all developer code resources are not part of XCode application). Could this be causing matplotlib to not find the MacOSX environment? Or am I missing a path or keyword in my bash environment perhaps?

[Matplotlib-users] cmap normalization question
Hi, I have been looking around but can't find what I want. I have two arrays, one with numbers from 0.02 to 0.20 and the other from 0.03 to 0.50. I am trying to plot them together with other arrays in a scatterplot where these two are the color term plt.scatter(x1,y1,c=myarr1,cmap=plt.get_cmap(gist_heat)) plt.scatter(x2,y2,c=myarr2,cmap=plt.get_cmap(gist_heat)) but it seems that each instance of the plot command rescales the array such that myarr1.max() and myarr2.max() are both with, which means that the two color scales are out of sync. Is there a way to force the two plots to respect the values in the array have the cmap go from 0 to 1, not from myarr1.min() to myarr1.max()?

Re: [Matplotlib-users] Plotting large images
That is what I was assuming, but it still seems a little odd that matplotlib generates that large of a memory footprint. Loading the fits file into the program using pyfits, with the code only uses 19MB of real memory and 600MB of virtual memory (strangly adding the line img = hdu[1].data, increases this to 208MB/800MB). Displaying images of various sizes I get these numbers from Activity Monitor Size Real Mem Virtual 3k x 3k 0.68GB1.57GB 4k x 4k 0.92GB1.80GB 5k x 5k 1.20GB2.10GB 5.5k x 5.5k 1.38GB2.28GB And the limit seems to be somewhere just above 5.5k by 5.5k (darn :( ) Cheers Tommy On Jun 30, 2009, at 7:27 PM, Perry Greenfield wrote: Because the image is so large, and matplotlib carries out various operations on the image (scaling, resampling, etc), it uses a lot of memory. This is one area where a specialized display program will be more efficient. If you need to use matplotlib, decide whether you really only want to display a subsection, or only need a lower resolution version (e.g., boxcar smooth and subsample) before displaying. I've found that image sizes well over 1kx1k can take some time to display, and those that are much larger can cause you to run out of memory. At least, that's what I think is happening.

[Matplotlib-users] x and y pointer positions
In a plot window (using Tkagg). just right of the menu the x and y positions of the pointer is shown when the mouse is in the window. Since I am using small windows this will change the size of the window. Is there a way to setthe format or remove this text?Cheers Tommy[EMAIL PROTECTED]http://homepage.mac.com/tgrav/"Any intelligent fool can make things bigger, more complex, and more violent.

[Matplotlib-users] Event handling for several windows
I have a program that uses matplotlib to plot two images. figim24 = figure(figsize=(5,5)) figim70 = figure(figsize=(5,5)) I want an event loop that will be able to register which of the two figures I mouse click in. When I only had one figure I used figim24.canvas.mpl_connect(button_press_event,clicker) but that obviously only register events in figim24. Can anyone guide me in the right direction for doing this?
