First question:I know I can do pylab.loglog() to get a loglog plot. I would like to create a loglinear plot. How can I do this? Second question: I would like to plot two sequences on the same figure with two different yscales, one scale shown on the left and one scale shown on the right. How can I do this? Thanks in advance, Jeremy

But now I come up with a separate problem. I have the following in my code: pylab.plot(n, S, 'b.', label='x') pylab.legend() ax2 = pylab.twinx() pylab.plot(n, mean, 'r',label="mean") ax2.yaxis.tick_right() pylab.legend() Both plots are shown with the appropriate axes, but only the second plot is listed in the legend. If I only have the first, then only the first plot will be listed. Please help. Jeremy

Is that possible? That's more desirable than two separate legends.
