figure: move line to second y-axis

Hello everyone,

when using matlab figures, is there a way to move only one signal/line to a second y-axis?

plotyy 

and

yyaxis

is no solution for me, because the figures are derived from the simulation data inspector and thus without workspace data.

I would have expected to find such controls in the property inspector, similar to the functionality in excel, where you can choose "show on secondary axis".

Can you manually scale the data?

How do you mean that? Currently I have to plot volume flow and pressure drop of a pipe network vs. valve setting.

pressure drop and volume flow on the same scale does not work (unbalanced). How could scaling help?

The following example shows how to transfer signals from 1 axes to other axes. First, create an example axes with two signals

fig = figure;
ax = axes();
hold(ax);
p1 = plot(1:10);
p2 = plot(rand(1,10));

Now you can transfer p2 to the right axes using

yyaxis(ax, 'right');
p2_new = copyobj(p2, ax);
delete(p2);

Note that if you don't already have handles of lines (p1, p2) then you can use findall() to get them.
