Details:

When running the demos in the contributed function confusionchart.m (patch
#9985) with Octave-7.0.0 on Windows the following error is emitted:

:
error: set.FontName: function called with too many outputs
error: called from
    set.FontName
    ConfusionMatrixChart at line 97 column 21
    confusionchart at line 125 column 6


When running the function in Octave-7.0.0 on Linux this error doesn't occur
and the demos work nicely.

I have no idea how to break this down into a smaller example, I'm not very
familiar with classdef.
So I can only offer the folowing steps to reproduce:
* download the confusionchart.m and ConfusionMatrixChart.m functions from
patch #9985 (attached for convenience here as well) into a folder in the
search path
* if needed install statistics package
* pkg load statistics
run demo 3:
Yt = {'Positive', 'Positive', 'Positive', 'Negative', 'Negative' }
Yp = {'Positive', 'Positive', 'Negative', 'Negative', 'Negative' }
cm = confusionchart ( Yt, Yp )
