Hi,
You could use another package, like openopt and the generic optimizers that
give you what you want provided that you create at least the gradient of
the function (I didn't create a class that can numerically derive a fit
function).
For instance
http://projects.scipy.org/scipy/scikits/wiki/Opt
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.

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

Stephen,
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).
It is possible to embed an MPL plot in a Cocoa application using the

I was just wondering what the status of the CocoaAgg backend is since

Can it be used interactively w/ipython?
Can it be used to embed mpl in a cocoa app and take advantage of all

Hi,
Is it possible to expand the colorcycle that matplotlib uses by default?
in axes.py, class _process_plot_var_args, def _clear_color_cycle(self) It
seems that self.colors are hardcoded to be self.colors =
['b','g','r','c','m','y','k'] ... is there a way to extend this? (Without

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.
