MATLAB: How to have arbitrary markers in ‘scatter’

Question

I would like the markers in a scatter plot to carry numerical and / or alphabetical information along with just showing their position in a 2D plane.

I have a set of 'x' values 1:100, with corresponding 'y' values y(x). In addition, different 'x' values point to different classes of objects. These classes could be identified with numbers ranging from -50 to 50. I would like my x-y scatter plot to be displayed with markers where each marker is a numerical symbol [between -50 and 50] identifying the class.

The function 'scatter' as set up currently only accepts a limited range of symbols as markers ('mkr'). It does not accept numerals (e.g. '1') let alone larger numbers (e.g. '123'). So I could not even set up a dumb / laborious process where 'scatter' plots one [x,y] pair at a time with its own marker.

Any help appreciated.

Thanks

Answer 1

For numerals and characters, text() them into place.

For general shapes, you will need to create one or more patch() objects.
