Charts need to be optimized in terms of aesthetics. The data needs to remain the same in each chart but presentation should be enhanced. All charts should include the percentage (not present currently but can be calculated from information inside chart) as well as the N for each bar (currently present).
The charts must stay in black and white. I am well aware of how to change the color/pattern of bars and other basic design elements. I am looking for a new way or better way to display the information other than the way I have it set up.
