Example Size Distribution Plots

Example shows how to plot up CCN droplet count in a size distribution plot. Also shows how to add different plot types together using assign_to_figure_axis.

display.plot_size_distribution('N_CCN_dN', 'droplet_size', time=t_ind, subplot_index=(0,))

# This part shows how you can use different display types in a single plot
# by assigning the new display object to a figure and axes from the first one.

display2.assign_to_figure_axis(display.fig, display.axes[1])
display2.plot('N_CCN_dN')

plt.show()
