How to display special types of symbols e.g. ♪ ?

12 views (last 30 days)
I need to display a series of symbols that have alt/ascii codes (e.g. ♪) onto a plot. I can already do this with symbols already in matlab, this is my code:
%plot 9 shapes on grid
clear all
x=[2, 2, 2, 3, 3, 3, 4, 4, 4];
y=[2, 5, 8, 2, 5, 8, 2, 5, 8];
figure (1)
plot (x,y, 'k+')
%set axes to show size
axis ([0 15 0 12])
%turn axes off
%draw rectangle around those shapes
figure (1)
myrectangle= rectangle('Position', [1, 1 ,4, 8], 'EdgeColor', [0 0 0])
But how do I replace the '+' signs with a '♪' ?

You can display text at a point by using the text() function instead of plot(), but there is no way to display unicode characters like the music note. Two options:
  1. The text() function can display other fonts, so maybe you can find a font that has a music note within the 0-255 ascii range.
  2. You can use the image() function to display a bitmap image, so if you make a little png out of the music note you can display them with image. But this might get more complicated if you have them close enough together that they overlap. (have to deal with transparency).
