Help with plotspread plot

Hi there, I have 3 groups of data A,B, and C and I want to plot A and B under the same category with different colors/markers. I want to use the plotspread function. How do I do that?

Are you referring to https://blogs.mathworks.com/pick/2012/09/07/beeswarm-plot/ ?

Yes. It’s that one

According to the documentation at the beginning of the function:

%       distributionColors : color identifier (string, cell array of
%           strings), or colormap, with a single color, or one color per
%           distribution (or per entry in distributionIdx). Colors the
%           distributions. Default: 'b'
%       distributionMarkers : string, or cell array of strings, with either
%           a single marker or one marker per distribution (or per entry in
%           distributionIdx). See linespec for admissible markers.
%           Default: '.'

So you can provide color and marker information for each distribution, using the same color or different color, same marker or different marker, according to your needs.

Yes. But I want to have 2 categories: one has distribution A and B, the other is distribution C. A and B will be plotted as one distribution with different markers. Could you provide an example?

[Walter Roberson]

Ah, A and B are to be plotted overlapping each other? I don't think the code can handle that.

This is kind of a hack, as plotSpread.m doesn't like when the xValues for each category are not increasing, so I just defined the first two categories to be very close together, then adjust the xticks after:

a = randn(50,1); b = randn(50,1)+1; c = randn(50,1)+2;
plotSpread([a,b,c],'xValues',[1 1.0001 2],'distributionColors',{'r','g','b'})
set(gca,'xtick',[1 2])
