<p class=MsoNormal><font size=2 color=navy face=Arial><span style='font-size:
10.0pt;font-family:Arial;color:navy'>Yes indeed plotting with unevenly spaced
axis is problematic in Matlab. The problem lies in the image (and imagesc) Matlab
functions that singleplotTFR and multiplotTFR call. These functions assume evenly
spaced axis, and they just interpolate linearly between lowest and highest
value. Therefore you cannot trust the values next to the axis when you look at
the blobs, because they can be totally wrong (which you will see if you change
the ylims, then the blobs shift). To get around this we used uimage and
uimagesc in fieldtrip, which works around this problem by making new axis
before calling image and imagesc. This was hard to implement in the current
version of multiplotTFR, so there we only give a warning (we’re working
on restructuring the plotting functions, so in the future hopefully this will
be also implemented in the multiplot functions). So although everything seems
to be going fine in multiplot, you can not trust the axis there, because they
are linearly interpolated!<o:p></o:p></span></font></p>

<p class=MsoNormal><font size=2 color=navy face=Arial><span style='font-size:
10.0pt;font-family:Arial;color:navy'>So for the error in the singleplot
function, there something is not going right when making the new axis. We got
the uimage and uimagesc functions as free functions from the matlabcentral
fileexchange (see url in the code). You could try to debug, and see why the new
axis making doesn’t work. I hope this helps to solve the problem, if not
let me know, I could try to help then.<o:p></o:p></span></font></p>
