uilineshift

function to shift a selected line (or all other outputs of the PLOT-function) in X and Y-direction

Description

 this function might be useful for quick and dirty visual inspection of multiple traces or timecourses with a timedelay between or arbitrary x/y-axes or illconditioned overlay of traces
 - works for all outputs of the 'plot-function' (type is 'line').
- Note, plotet dots are also of type line.
 - The function adds an icon in the menubar of a figure, which than
   activates the shift-function
 - if the function is active, a line can be selected and moved within the axis as long as the
    mousebutton is not released
 - right mouse button (contextmenu): get the original plot (as long as the icon in the menubar is
   not deactivated)
=====================
HOW TO DO:
1]
plot(something);%plot something
uilineshift; %adds icon in menubar
OR 2]
uilineshift; %adds icon in menubar
now plot something
=====================

Extremely useful. I don't know how many times I have had to do this manually.

It would be nice if this worked for simulink scopes.

I thought is would be useful to show the difference between the current line and the original lines. This would be useful if you are trying to find a offset value for instance. If you add this after line 248 or so then the difference will display in the command window:

x_diff = s.x(1)-s.xorig(1);
y_diff = s.y(1)-s.yorig(1);
disp(['New Location Difference: x: ',num2str(x_diff), ' y: ',num2str(y_diff)])

This was a quick and dirty way to get the difference. Better yet the difference would display on the plot somehow.

Nice, but the demo requires "hanning", which is a signal processing toolbox function.

Very Nice. I disabled the x-axis by remming out lines 231,250,251,274. Since I normally plot using semilogx, the x axis shifting doesn't work well as is. An option for x or y only shift would be nice. A little display showing the current value of shift would be nice too. Very usefull as is though...
