Hi Shrividya, Here's how I interpreted what was being asked, in case that helps. Also, Eric, is there a reason we make an outline instead of just cbar.ax.set_frame_on? - My manual adjustments screw up and confuse whatever data cbar.outline depends on x = np.random.rand(100) y = np.random.rand(100) z = np.random.rand(100) collection = plt.scatter(x, y, c=z*350, vmin=0, vmax=350) cbar = plt.colorbar() cbar.ax.set_ylim(cbar.norm((300,350))) cbar.ax.set_xlim(cbar.norm((300,350))) # maintain aspect ratio cbar.set_ticks(np.linspace(300,350,6)) # didn't see a quick way to fix the outline cbar.outline.set_visible(False) cbar.ax.set_frame_on(True) plt.draw() best, -- Paul Ivanov 314 address only used for lists, off-list direct email at: http://pirsquared.org | GPG/PGP key id: 0x0F3E28F7
