Details:

Given two datasets with different classes, scatter seems to be doing something
funny with it:


graphics_toolkit fltk;
x = rand(10) * 3;
y = randi ([0 255], 10, "uint8");
figure; scatter (x(:), y(:));
figure; scatter (x(:), double(y(:)));


It would appear that it casts the x data (class double), to uint8 (the class
of y) since all x values are plotted as integers.
