this is ploting an array with -inf in it, which is ignored by plot.
It then is plotting the next value (for instance -1) so it is fine.
You are explicilty telling the plot command to plot from -inf to 70,
which it cannot do.

how about setting range = [min(loglevels[0,70.7107]),
max(loglevels[0,70.7107])] ?

Cheers,
bob
