Asked by Benjamin on 15 Aug 2011

I am trying to plot four plots in the same figure. First i plot using plotyy. Then two graphs are created, each with a yaxis.

Now I want to plot another two plots. One using yaxis-1 and one using yaxis-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.

Thanks :)

Ben

Accepted answer

[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.

figure [hax12 line1 hline2] = plotyy(1:10,1:10,1:10,2:11)

set(hax12,'NextPlot','add')

plot(hax12(1),1:10,3:12) plot(hax12(2),1:10,4:13)

I mean:

[ax,h1,h2] = plotyy(...)

hold on

plot(ax(1),...)

plot(ax(2),...)
