Hi,
i tried to solve my problem but could not find any solutions.
The problem: If i plot two data sets with two different y axes, the subsequent plots also have two y axes. Example:
x = 1:10;
y1 = x.^2;
y2 = x;
hold on
yyaxis left
plot(x,y1)
yyaxis right
plot(x,y2)
hold off
plot(x,y1)
I tried to insert the hold command on different positions but everytime the next plot isn't working as i want it to:
So my question is, how do i get a "normal" plot after yyaxis was used.
The answer is probably very easy, but I'm not very into MatLab yet, so sorry in advance for this question ._.
If the question was already asked and answered a link to that discussion would be helpful as well :)

You are using LiveScript, which has its own rules for deciding when to plot things or not.
Experiment with using
clf
at the point that you want to switch back to single axes.

this tip should be mentioned in the yyaxis function description, because after using it, the graph is repeated randomly in a sort of glitch

Instead of clf, you can also use:
cla(gca,'reset')
The benefit of that is if the axis is inside a GUI and not a Matlab figure, or if the figure has additional children aside from the axis.

No, in this case it is not enough to cla. When you use plotyy(), two axes are created, and cla() will not get rid of the other one.

That's why reset is there. The documentation says so (at the very bottom of the page).

Also, I have been using it and it works.
