How can I plot multiple graphs on the same figure using plotxx?

Hey guys!

I'm new to Matlab and have a question. I basically need to plot several profiles of 2 different variables on the same figure. So I downloaded plotxx, which worked perfectly to plot one profile of each. But when I try to use hold on, and add more plots, it doesn't work as well. Can someone give me some help? That's what I have been trying:

[ax,t1,s1] = plotxx (x1, y1, x2,y2, xlabels, ylabels)

axx = ax(1);

set(ax(1),'YDir','reverse','YLim', [0 200], 'xlim', [15 25])

set(ax(2),'YDir','reverse','YLim', [0 200], 'YTickLabel',' ','xlim',[-50 50])

hold on

plotxx (x3, y3,x4,y4, xlabels, ylabels)

in which, all the x's and y's should have the same axis.

Larissa - do your original plots "disappear" because of the call to plotxx or to changing the limits on the axes?

No, but the numbers and labels on the axis appear on top of each other, in the wrong places.

[ax,t1,s1] = plotxx(x1, y1, x2,y2, xlabels, ylabels)
set( ax(1),'YDir','reverse','YLim', [0 200], 'xlim', [15 25])
set( ax(2),'YDir','reverse','YLim', [0 200], 'YTickLabel',' ','xlim',[-50 50])
hold( ax(1), 'on')
plot( ax(1), x3, y3);
hold( ax(1), 'off');
hold( ax(2), 'on')
plot( ax(2), x4, y4);
hold( ax(2), 'off')

Thank you so much, Walter! Worked perfectly!
