CBNEEDLE is used to create a 'needle' or an indicator on a colorbar. Currently, the possible input combinations are: none (searches for a colorbar, adds needle at average y value), handle for colorbar axis (adds needle at average y value), y value (searches for colorbar,adds needle at specified y value), colorbar axis and y value. Output is handle to 'needle' (patch object).
Examples:
surf(peaks); c = colorbar;
%add needle at middle point
cb = cbneedle;
delete(cb)
%add needle to 'c'
cb = cbneedle(c);
delete(cb)
%add needle at 3
cb = cbneedle(3);
delete(cb)
%add needle to 'c' at 5
cb = cbneedle(c,5);
delete(cb)
