Thread Subject: Datetickzoom.m and 1) 2 y-axes 2)rotate Xticklabels

I am rather new to MATLAB and am slowly learning my way around it.

I have been using the datetickzoom.m file for my data and it works great when I have an x-y plot (temperature or flow rate etc vs time) and need the date to adjust when I zoom in and out. I have now run into a few (2) limitations of the file and would like to know how to circumvent these problems in as easy a way as possible.

1. I would like to rotate the Xticklabels. I have tried implementing xticklabel_rotate90.m and rotateticklabel.m, but can't seem to get either of them to work when using datetickzoom.m. I would really prefer to use rotateticklabel.m because I would like the freedom to rotate my Xticklabels less than 90 degrees. Any ideas???

2. Graphing 2 y-axes and one x-axis using:
[AX,H1,H2] = plotyy (x1,y1,x2,y2)
When I use datetickzoom and this function, the dates for x1 are changed, but not x2 and it looks bad. Can I link x1 and x2 Xticklabels together? They should be the same datenum (date) value. If so, what would be a (SIMPLE??) way to do this?

Cheers

In theory, you should be able to use linkprop() to do that, if you have a
new enough version to support linkprop().

You may try TLABEL:

http://www.mathworks.com/matlabcentral/fileexchange/loadFile.do?objectId=19314

it uses datetickzoom and links axes (I have a new version but I hadn't updated yet).



> 1. I would like to rotate the Xticklabels

Change the following lines in datetickzoom or tlabel:

set(zoom(axh),'ActionPostCallback',@datetickzoom) set(pan(get(axh,'parent')),'ActionPostCallback',@datetickzoom)
or
set(zoom(axh),'ActionPostCallback',@tlabel) set(pan(get(axh,'parent')),'ActionPostCallback',@tlabel)

For:
set(zoom(axh),'ActionPostCallback',@tlabelrot) set(pan(get(axh,'parent')),'ActionPostCallback',@tlabelrot)

And you need to create and save the function:

function datetickzoomrot
tlabel
rotateticklabel


Get the idea? Hope it works...

OK Carlos, thank you!

I followed your instructions but im still not getting it. Renamed tlabel.m to tlabelrot.m, and followed your instructions above. How do i input the rotation angle? Still unclear. Does tlabel link my axes as well??

Oh yes, you are right, one should check the inputs of the rotations functions. But the idea is that you need to create a function CALLBACK (at least 2 entries HANDLE + EVENT) and put its handle in those lines (do not rename tlabel!).

Inside that function you may put rotate, tlabel etc etc, with arguments you like.

Well, think about it...
