How to plot 3 y axis or more in a single graph?

For example: I have to plot X=(1:1:50); Y1=sin(X); Y2=exp(X); Y3=(X).^2; For y-plot I want respective adjusted range of axis.

[Roy Kadesh]

What do you mean? Do you mean you want to plot 3 lines in one figure?

[UTKARSH VERMA]

I want 3 line in one graph but with 3 axis representing their respective line. For example for Y1 yaxis value range should of range between -1 to 1 but if i use exp(i.e. Y2) axis to represent Y1 then it may give straight line.

Use this function from the file exchange https://in.mathworks.com/matlabcentral/fileexchange/9016-addaxis

plot((1:5),randi(25,1,5),'r')
addaxis((1:5),randi(25,1,5),'g')
addaxis((1:5),randi(25,1,5),'m')
addaxis((1:5),randi(25,1,5),'y')
legend({'plot1','plot2','plot3','plot4'})

It's working, thank you.

Hi, I tried to use the above mentioned function from the files exchange. And tried to use it in the way Ankur has coded. However I am getting a few errors -

Error using matlab.graphics.axis.Axes/get

There is no colorord property on the Axes class.

Error in aa_splot (line 13) cord = get(gca,'colorord');

Error in addaxis (line 135) hplts = aa_splot(varargin{:});

[Milad Hamidi Nasab]

I receive the same errors. Is there any way to just add some axes easily without going through 200 code lines and get exhausted?

[Malik Tahiyat]

replace all 'colorord' in aa_splot.m to 'ColorOrder' and it would work.

[Franziska Ba]

I already have changed the 'colorord' to 'ColorOrder', but I am getting still the following error:

Error in addaxis (line 112) hplt = plot(varargin{:});

[andre contini]

I changed 'colorord' in aa_splot.m to 'ColorOrder' and it works well.

tks @Franziska Ba

[jasongrig]

how can I select whether the new axis goes to the left or right side of the plot?

[Robert Wei]

This function has a major bug - when you pan around, only one of the axes (primary axis) updates. the others do not

[Adam Danz]

Here's are methods that pan and zoom correctly

[Alessandro De Iasio]

Was anyone able to plot more than one curve for the nth axis?

Do you mean something like https://www.mathworks.com/matlabcentral/fileexchange/46688-jzplotys-zip or https://www.mathworks.com/matlabcentral/fileexchange/9016-addaxis? Or https://www.mathworks.com/help/matlab/ref/yyaxis.html (this one creates 2 axes only)?

[UTKARSH VERMA]

Yes, I mean this https://www.mathworks.com/matlabcentral/fileexchange/46688-jzplotys-zip . Is there any command like plotyy for two y-axes?

[Rik]

If that submission works for you, why not use it? Or is your question how to use that function?

[UTKARSH VERMA]

Yes, I want to know how to use that function.

[Jan]

Simply download it and call it. The help section of this function explains the details. Or see the suggestion of ANKUR KUMAR.

plot((1:5),randi(25,1,5),'r')

addaxis((1:5),randi(25,1,5),'g')

addaxis((1:5),randi(25,1,5),'m')

addaxis((1:5),randi(25,1,5),'y')

legend({'plot1','plot2','plot3','plot4'})
