Question
I am trying to plot four plots in the same figure. First i plot using plotyy. Then two graphs are created, each with a y-axis. Now I want to plot another two plots. One using y-axis-1 and one using y-axis-2. How do i do this? If I do   [ax,h1,h2] = plotyy(...) hold on plot(ax(1),...) plot(ax(2),...) i don't get all four plots.

[ax,h1,h2] = plotyy(...) 
hold(ax(1))
plot(ax(1),...)
hold(ax(2))
plot(ax(2),...)

The problem was simple, hold on just holds the current axes and your plotyy makes two axes so only one is the current.
