Hi!

I want to plot three datasets on top of each other (same plot not subplots). Each has its own units so I want to have two different axes/scales on the left side and one on the right. I know how to plot double axes with yyaxis left and yyaxis right. Can I do two yyaxis left lines or something?

在 MATLAB Online 中打开

To plot three datasets on top of each other, set hold command to ON after creating axes object.

axes;      
hold on; 

The axes command creates an axes object with y-axis on the left by default. Then a yyaxis left and yyaxis right can be used to create another y-axis on left and a y-axis on right respectively.

Your link only shows how to create a plot with two yaxis, one on the left and one on the right respectively. So does your example. The question asked how to create a plot with three yaxis in the same axes.

Is there a way to plot three yaxis into the same axis, e.g. with ticks going in and out on the side with two yaxis?
