Here are my questions !

How can I add third Y-axis in same plot

Here in data 6 variables(dt,temptime,Tout,RHout,Sat,mix) are present and I would like have

dt & temptime variables in x-axis

Sat & RHout in yyleft axis

Tout in yyright axis

mix in yyright as third axis

So what did you try and where did you have a problem?

Hope this helps:

fig=figure(1);
yyaxis left
plot(dt,Sat,'b--','Linewidth',2);
% hold on;
% plot(temptime(3470:3578),RHout(3470:3578),'b.','Linewidth',2);
ylabel('Saturation and RH');
hold on;
yyaxis right
plot(dt,mix,'r-','LineWidth',2);
hold on;
plot(temptime(3470:3578),Tout(3470:3578),'r.','LineWidth',2)
xlabel('Time (h)'); % 
ylabel('Mixing ratio [Kg/Kg]');
set(gca, 'YScale', 'log');
grid on

I don't think I have seen or known how to do anything like that. Sorry! I would like to know/learn if that's possible as well.

One way might be to rescale the 'Tout' data to the same scale as 'Mix' and plot it. Still I don't think you can assign two different ylabels to the same axis. But again, I might be wrong.

If you find out my answer is okay, please accept as an answer. If you liked the conversation, please vote up as well. Thanks!

There's not a function supplied with Matlab to have more than the left/right axis.

You either have to "roll your own" by shrinking the existing axis in the x direction enough and creating a new one or use one of the FEX submittals. I know there are some over there but I've not used any so can't recommend any particular one as the gold standard.
