Hi JJ,
I'm not sure I understand how to properly set the axe_locator. Below
is my snippet of code that I use to create my contourf plot and then
create the colorbar. I'm unsure how I would modify it to do as you
suggested. Any help would be appreciated.
plot = ax.contourf(xc, yc, data, cmap=cmap, levels=clevels)
cax = plt.axes([0.85, 0.125, 0.035, 0.325])
cbar = fig.colorbar(plot, format='%.1f', cax=cax)
I should also point out that the reason I'm not using the axes_grid
toolkit is because I'm constrained to develop based on the current
Enthought release.
