Ok.  This is done.  These all work (for gnuplot):

plot2d(1.5^x,[x,0.001,20], [logx, t]);
plot2d(1.5^x,[x,0.001,20], [logy, t]);
plot2d(1.5^x,[x,0.001,20], [logx, t], [logy, t]);

For each of these, the appropriate axis (or axes) are logarithmically
scaled by gnuplot.  And enough samples are taken of the x axis to give
a smooth plot.

I'll be checking this change in shortly on the main branch.  This is
only for gnuplot.  I didn't try to make it work for any other plotting
method since I don't use or don't have them.
