I have the CocoaAgg backend specified in matplotlibrc in ~/.matplotlib/ as:
backend : CocoaAgg
However, when I plot, matplotlib uses the TkAgg backend in spite of this.

The following run well . But I just want to make the image, with the x and y
as axis and z as the image value ,show on the figure. In the pylab , we can
just give a command imshow ,But here , I fail to do it , I have try
ax.imshow() again and again ,but fail. Can sb give me some advice . Thank
I was just wondering what the status of the CocoaAgg backend is since
there is not much info available.
Can it be used interactively w/ipython?
Can it be used to embed mpl in a cocoa app and take advantage of all
the xcode/interface builder stuff in OS X?
Thanks-

hi,
I think the new 0.91.1 has some kind of file handle leak at least when
using python 2.4, tkagg, and within ipython. Using process explorer to
look at filehandles opened by python then I get about 25 new open
handles to vera.ttf per %run of the following script.

Thanks for the background Barry.
I was asking because I have a bit of image processing/analysis code
(numpy/mpl/pil) that I would like to build a GUI front-end for. As I
am a recent convert to the osx world, I thought it would be very slick
to be able to do this with the xcode/IB tools. Since
I primarily follow the dev list, but you've caught my eye. ;)
So to be clear, you would just like me to install some other tcl/tk
before I do the official matplotlib osx binaries. What package
should I be installing and where should I get it from. As long as it
still works with the bundled
I feel we're getting a tad bit off topic from my original inquiry. Does
anyone have an answer for me? Thanks.

The CocoaAgg backend is not supported in IPython. You can use it in
the non-interactive form (i.e. with a pylab.show() but you will have
to close the window in order to return control to the IPython shell).

Hi,
I have (x,y) data that I want to fit to the formula
y = a * x^b
to determine a and b. How can I do it? The current
manual only lists linear fit and polynomial fit.
Or, putting it in a more general setting, is there a
module to do fitting to an arbitrary function?
It would be something like
Ping,
You should investigate scipy.optimize.lsqFit for using least squares
to fit an arbitrary function and scipy.odr for regular or orthogonal
least squares fitting.
