plots.m, plotses.m

Plots each column of a matriz vs a single axis. Improvement of plotyyy.

Description

Example:

x = [-10:0.1:10]';
Y = [x x.^2 x.^3 cos(x)];
location = 'top';
labels = ['x-axis '
          'y=x '
          'y=x^2 '
          'y=x^3 '
          'y=cos(x)'];
[hlines,haxes]=plots(x,Y,location,labels);

Plots the columns of the matrix Y versus the vector column x, using different axes at the top of the figure, with the specified axes-labels.
    
The location of the axes can be 'left' (default), 'right', 'top' or 'bottom'.

PLOTSES.M its the almost the same but with the axes moved from the fixed axis (useful?).
  
Both M-files come with the colored example of the screenshot.

A great and clean job. Finally I dont have the limitations of plotyyy, plotxx with the number of axes and their LOCATION! Thanks!

[Matt Williams]

I couldn't get it to work, except for the example. Kept getting the error:

??? Error using ==> set
Width and height must be > 0.

Error in ==> plots at 62
set(gca,'Position',pos_fix); % New position

Mostly very good and clean. However, no easy way to set YDir to reverse. Will cause curves to not plot on comon axes

[John M. Burton]

It does exactly what I was looking for.

How do you handle zooming?
(linkaxes does not work properly)

[Carlos Adrian Vargas Aguilera]

To be honest, I dont't remember Thierry. Probably, it cannot handle zooming.

How to set the range for each axis? Thanks

[Carlos Adrian Vargas Aguilera]

You just need to use >> set(he(1),'Xlim',[0 1]), to modify the limits of the first axes from 0 to 1. Carlos

[Carlos Adrian Vargas Aguilera]

To use 'reverse' in 'YDir' (or in 'XDIr' if 'left' o 'right' was used) in the included example use:

bt = 2; % 1=='bottom', 2=='top'
ylim = get(he,'YLim');
N = length(he);
for k = 1:N
 d = ylim{1}(1,bt)-ylim{k}(1,bt);
 ylim{k} = [ylim{1}(1,1)+d*(bt==2) ylim{1}(1,2)+d*(bt==1)];
end
set(he,{'YDir','YLim'},[repmat({'reverse'},N,1) ylim])

Cheers, the author

very good job, thank u!

[Edward Steele]

A very versatile m-code: excellent! I was especially impressed that this code is able to be easily adapted to layer multiple x- or y- plots onto other types of figure (e.g. bar / barh) using your 'pos0' and 'pos_new' variables. Cheers! -ES
