Sequential colormaps are ideal for 12 | representing most scientific data since they show a clear progression from 13 | low-to-high values. 14 | 15 | Diverging: 16 | These colormaps have a median value (usually light in color) and vary 17 | smoothly to two different color tones at high and low values. Diverging 18 | colormaps are ideal when your data has a median value that is significant 19 | (e.g. 0, such that positive and negative values are represented by 20 | different colors of the colormap). 21 | 22 | Qualitative: 23 | These colormaps vary rapidly in color. Qualitative colormaps are useful for 24 | choosing a set of discrete colors. For example:: 25 | 26 | color_list = plt.cm.Set3(np.linspace(0, 1, 12)) 27 | 28 | gives a list of RGB colors that are good for plotting a series of lines on 29 | a dark background. 30 | 31 | Miscellaneous: 32 | Colormaps that don't fit into the categories above. 33 | 34 | """ 35 | import numpy as np 36 | import matplotlib.pyplot as plt 37 | 38 | #
