PLOTXX Create graphs with x axes on both top and bottom

File Information
Description

PLOTXX Create graphs with x axes on both top and bottom
 
Similar to PLOTYY, but ... the independent variable is on the y-axis, and both dependent variables are on the x-axis.
 
For example, you may wish to plot temperature and salinity as a function of depth in the ocean. In the atmosphere, plot temperature and relative humidity as a function of altitude, etc.

Can someone help me??I´m trying to use this rotine with subplot, but I can´t do this and I saw another comments about this!Thank you

very useful but sloppy code...
Could have done better...
Yet very useful

% This works at least:

set(findobj('Type','line'), 'LineWidth',lw)

% From web('jar:file:///C:/Program Files/MATLAB/R2009b/help/techdoc/help.jar!/ref/set.html', '-helpbrowser')

Is it possible to make a bar graph and a line graph with different x axes on the same figure using this program? Thanks.

Good stuff. How can I make it work for inversely proportionnal axes : i.e. wavelength (in microns) and wavenumbers (in cm^-1) ?

thanks a lot for this solution ! (very usefull for vertical profiles)

add
set(ax(1),'XLim',[min(x1) max(x1)]);
set(ax(2),'XLim',[min(x2) max(x2)]);

to get autoscale on both x axis

or you may prefer to use :
[low,high,ticks] = bestscale(ylim1(1),ylim1(2),ylim2(1),ylim2(2),islog1 | islog2);
with
set(ax(1),'XLim',[low(1) high(1)],'XTick',xticks1);
set(ax(2),'XLim',[low(2) high(2)],'XTick',xticks2);

if you want to get a better ticks layout

(see open plotyy to copy bestscale sub function)

very useful thanks

add
set(ax(1),'Box','on','ActivePositionProperty','position')
to get the position right
add
set(ax(2),'YAxisLocation','right','Color','none', ...
'XGrid','off','YGrid','off','Box','off');

To use with subplot, you need to comment out

set(ax(1),'Position',[0.12 0.12 0.75 0.70])

on line 65.

Is it just me, or does this not work with subplots?

24 Oct 2006 Peter Burns

To avoid inconsistent axes ranges, I suggest calling
> axis tight
after plotxx. You might consider adding this to the function as a precausion.

Useful as a corollary to plotyy. Would be useful to have two inversely proportional axes for one plot (e.g., wavelength on bottom and energy on top). Though this isn't too hard to do from plotxx. Thanks!

Thanks, saved me a lot of programming

02 Feb 2005 Izru Garner

Well done Dennis by your scripts, I agree with Lina Chang.

useful programme

18 Jun 2003 Sachin Chandra

Very useful. I often why mathworks didnt have a function similar to plotyy..
I think additional parameters like passing colors,line width can be helpful too..

16 Mar 2003 Lina Chang

Very helpful for creating nomographs. Thanks.

Updates

modifying description

02 Nov 2001

Two new input arguments have been added to ease the task of labeling the axes.
