How do I hold the current plot but not the axis properties?

I'm creating a GUI that can plot multiple functions on the same plot, depending on which data-set I choose. If I use hold on, the axis on the plot doesn't change and the next data-set might not be completely displayed. I want to keep the current data on the plot but have another data-set plotted and have the axis scale so that both sets can be seen.

Check to make sure that your axes XLimMode and YLimMode is set to auto.

figure;plot(1:10)
hold on;
plot(1:10:100)
plot(1:.1:10)

seems to work fine, so your issue may not really be with the hold command.

Yup, that works. I'm having trouble with using a polar plot.

figure;
polar(1:10)
hold on;
polar(1:10:100)

This runs into the same problem I'm having. If I use axis auto, the polar(1:10:100) fits in the plot but the axis doesn't scale properly.
