scatterhist problem 'color value must be a 3 element vector'

When I try this: ( http://ch.mathworks.com/help/stats/generate-correlated-data-using-rank-correlation.html )

rng default  % For reproducibility
p1 = pearsrnd(0,1,-1,4,1000,1);
p2 = pearsrnd(0,1,0.75,3,1000,1);
figure
scatterhist(p1,p2)

It gives me:

Error using matlab.graphics.chart.primitive.Histogram/set
While setting the 'FaceColor' property of Histogram:
Color value must be a 3 element vector

Error in internal.stats.plotGroupedHist (line 130)
            set(hXLines(i),'FaceColor',clr(i,:));

Error in
scatterhist>@()internal.stats.plotGroupedHist(x,grp,'NBins',xbin,'Color',clr,'DisplayStyle',style,'Norm','pdf','AxisOn',false,'PlotGroup',plotGroup)
(line 299)
                Xfunc = @()internal.stats.plotGroupedHist(x,grp,'NBins',xbin,...

Error in scatterhist (line 384)
    Xfunc();

WHY? How can I solve?

It works for me. Can you post the output of

which -all scatterhist

[condor]

C:\Program Files\MATLAB\MATLAB Production Server\R2015a\toolbox\stats\stats\scatterhist.m

[George]

Do you know why that's in a MATLAB production server subdirectory? Mine is just in the stats toolbox directory.

[condor]

I don't know ... but everything has always worked perfectly!

Do you think this may be the problem?

[Walter Roberson]

I have seen an increase over the last few months in the number of installations showing up as MATLAB Production Server . It probably makes no difference.

Please check

which lines

The expected location is toolbox/matlab/graph3d/lines.m

[condor]

no I have another one ... this: >> which lines C:\Users\mauro\Desktop\MATLAB\MATLAB_Generale\PERIZIE\Anatocismo\OCR\lines.m

condor, you need to do one of the following:

1. delete C:\Users\mauro\Desktop\MATLAB\MATLAB_Generale\PERIZIE\Anatocismo\OCR\lines.m -- which would probably interfere with using that software
2. rename that file to something else -- which would probably interfere with using that software unless you edited all of the code in that package to use a different name
3. use pathtool to move that OCR directory to below the Mathworks-supplied directories -- which would probably interfere with using that software
4. use pathtool to remove the OCR directory for you MATLAB path -- this would require that you cd to that directory to run the software
5. create a subdirectory named private in C:\Users\mauro\Desktop\MATLAB\MATLAB_Generale\PERIZIE\Anatocismo\OCR and move the lines.m file to that subdirectory. In theory that should allow that software to work without changing anything else

Genius! Thanks Walter!!! PS How do I select your answer?
