Why does scatter now return an error

I'm trying to use scatter in the same way I've always used it, to plot data in color, as in:

scatter(x,y, sz, dat,'filled')

where x, y and dat are m x 1 vectors and sz is just a single value (i.e. sz = 20). I get the following error:

Color must be one RGB triplet, an m-by-3 matrix of RGB triplets with one color per scatter point, or an m-by-1 vector with one value per scatter point.

This error occurs now with code I've run for years.

I recently had to reinstall Matlab due to a laptop failure and I'm using R2024b Update 2 on MacOS 15.1.1

Thanks.

It seems to work for me, though I am on R2024b no update, but otherwise the same as you.

Could you provide the input variables used in scatter that reproduce the error?

[Geno]

Really can be any collection of usual vectors that have always worked, but here's one:

x = 1:100;

y = sin(x);

z = x.^2;

figure

scatter(x,y,20,z,'filled')

This is the scatter function being called:

/Applications/MATLAB_R2024b.app/toolbox/matlab/graphics/graphics/scatter.m

Answer 1

[Walter Roberson]

Please show the result of

which -all height
which -all width

You would encounter the RGB error if either height or width are not the MATLAB built-in functions.

[Geno]

That did it. I had an old height.m in my path. Once I deleted that, scatter works again.

Thanks much!

Impressive, @Walter Roberson

I need to get a crystal ball toolbox license.
