error message from hist

Hello,

I tried to plot a histogram of my array MCResult
octave:3> size(MCResult)
ans =
   1000      3      2

octave:4> max(MCResult)
ans =
ans(:,:,1) =
   3.2412e+05   1.0930e+05   1.0930e+05
ans(:,:,2) =
   446.555    84.306    84.306

octave:5> min(MCResult)
ans =
ans(:,:,1) =
   2.1226e+04   3.2322e+04   3.2322e+04
ans(:,:,2) =
  -38.379  -29.447  -29.447

with the following command:

octave:3> hist(MCResult(:,:,2),[-30:5:300])
error: number of columns must match (1 != 3)
error: evaluating argument list element number 1
error: evaluating if command near line 94, column 3
error: called from `hist' in file `/usr/share/octave/2.9.12/m/plot/hist.m'

unfortunately, this did not work.
The command hist(MCResult(:,:,2),[-30:20:300]) worked however fine.

I changed therefore the number "30" in line 94 of file `/usr/share/octave/2.9.12/m/plot/hist.m' to "3000" thereby accepting the slower algorithm.

And voilà everything o.k. but a bit slower...

Bye
