I have generated bar graph with colors using my code and is of good quality.To convert the color graph into patterns i used the command
fH = gcf; colormap(jet(3));
applyhatch_pluscolor(fH, '-x.', 0, [ 0 1 0], jet(3));
when i run the code, i can get the graph where the color of the bar gets convereted into pattern but the quality of the graph is poor.
could anyone please help me how to improve it.
