addaxis

Add multiple y-axes to plots. zoomable with zoom modification.

Description

Adds multiple axes to plots using addaxis.m. Automatically adjusts axes to accomodate as many axes as you want.

Add more plots to any added axes with addaxisplot.m

Add y-labels to any of the axes with addaxislabels.m

All plots zoom together. A small modification to the zoom function allows all of the added axes to update with zoom.

zoom modifications for R11.1 and R14SP2 are included.

Usage is almost exactly like the plot command, see the help for addaxis.m for examples.

• MATLAB release: MATLAB 5.3.1 (R11.1)

A really superb tool. Just what i was about to write on my own. Thank you!

I would just allow the user to choose the color of subsequent plots to the same additional axis (addaxisplot line 43) and not force them to be the same color as the axis.

A nice tool thank you,
It is better not redefine splot.m which is used for plotting freq and time resp of system SYS,
Just rename to say splot__.m and use

Best among the posted on the website for adding secondary axis or zooming.

I wanted to plot several curves and then add another one on a second y-axis. Tried plotyy and a few different tools and finally used this. Works ok if you don't mess with the orignal axis after adding the second. However, like some other tools it affects the size of subplots with some of them being slimmer or flatter, at random, which means you need to resize manually. Also the second axis is shifted slightly upwards. Other tools seemed to have similar problems, so I wonder whether that has some other cause (thus 4*). Using Matlab 7.0.4 on X11. Nevertheless I get usable graphs.

nice tool. it is too shame that you can not add x axis, that is what i'm looking for

Best to fix the plotyy bug

[beckali abdel]

useful, thanks

[Ian Howat]

Great tool. Much^10 easier to use than plotyy. I agree with fabiano that a good modification would be to add multiple horizontal labels.

[Xianyu Zhao]

Very useful, thanks a lot

[Wang Ding]

a very useful tool! Thanks a lot

I think this is a very useful tool, but I guess I have some problems, because there are always error messages when I am using the zoom function. Perhaps it is because I am using the new version of MatLab but I do not know exactly because I have got the software since only a few days. Perhaps anybody can help me.

[Amir Abbas Zadpoor]

Well done! Thanks a lot

Hi. This is a great tool, I used it to create something more specific for my needs, so thank you for the ideas. I'm wondering if anyone has figured out a fix to a legend..I can only add to the legend the number of entries on the left side.

[Ian]

Hi, good tool.
Is it possible to make some of the additional axis use a log scale?

[Andres]

A good multiple y-axis tool - it could be a bit more customizable. Use linkzoom ( http://www.mathworks.com/matlabcentral/fileexchange/21414 ) to avoid the zoom modification, or use Carlos Adrian's derivative (not tested yet).

Great work!

Great Tool. Would be great if you could update the zoom functionality to more recent versions of MATLAB.

Great tool! I'm surprised matlab doesn't handle this better natively (the way gnuplot does).

If you need to change linestyles, ytics, etc, just change the declaration of addaxis to:

function [hplts,h_ax] = addaxis(varargin)

This give you back the handle to the plot (as if you called h=plot(...)) and the axes (h=axes(...)) yourself.

The only outstanding issue I have is positioning a legend outside the plot...one solution might be to put all the new y-axes on the right (instead of alternating left/right), and then legend Location NorthEast, but I haven't tried that yet.
