[Octave-patch-tracker] [patch #9985] [octave forge] (statistics) Add function confusionchart

[anonymous]

Follow-up Comment #14, patch #9985 (project octave):

On 6.x and older it works. It is certainly this part (line 821):

num2str (l_rs(nonzero_idx))


Where "l_rs(nonzero_idx)" is a column of numbers and "num2str
(l_rs(nonzero_idx))" is a matrix of characters, e.g.:

>> num2str ([1;21;3])
ans =

 1
21
 3


The "text" function of line 820 should return an array of "text" graphics
objects with the x, y, and label properties determined by each line of "x_rs",
"y_rs", "l_rs". A "for" statement could easily overcome the problem, but it is
nicer this way, I think.
