MATLAB: Scatter plot custom colors

Question

Assume

a=[1 5 7 1 3 9 4 6 8 7];

b=[4 5 6 7 2 6 9 4 2 1];

c=[1 2 0 1 0 2 1 1 0 1];

scatter(a,b)

How can I now color the dots using a color code from 0 to 2 corresponding to the values in c?

Answer 1

3rd argument is variable size and 4th is variable color.

scatter(a,b,[],c,'filled')

where 'filled' is optional.

If you want another set of colors, just set a different or custom colormap (default is parula)
