Hi,

I'm trying to generate a contour plot with logarithmic axes. I'm

generating data on a grid defined by logspaces:

x_range = logspace(log10(xstart),log10(xend),num=25)

y_range = logspace(log10(ystart),log10(yend),num=25)

Then, to generate the plot I do the following:

[X,Y]=pylab.meshgrid(log10(x_range),log10(y_range))

pylab.contourf(X,Y,transpose(data))

And to obtain nicer tick mark labels, this dirty way:

xmajorForm = pylab.FormatStrFormatter('10e%.1f')

ax.xaxis.set_major_formatter(xmajorForm)

ymajorForm = pylab.FormatStrFormatter('10e%.1f')

ax.yaxis.set_major_formatter(ymajorForm)

Are there better ways to (1) set the x and y xis scaling to

logarithmic, and to (2) obtain nicely formatted tick mark labels ?

I tried playing around with the x and y axis data and with LogLocator

and LogFormatter but it doesn't seem to do the job.
