Hi,
I would like to plot two curves on the same graph using the autograph
subroutines. I would like one curve to be scaled by the left axis and
the other by the right axis. I've figured out how to turn on the right
axis correctly and to get the axis labels to have the right values, but
I am having trouble setting the size of the labels on the right axis.
Below is a sample program that illustrates my problem. Note that the
labels on the right are much smaller than those on the left, bottom and
top even though I am using the same resizing commands for all sides.
What am I doing incorrectly?
Thanks.
-Harry
