python: how to plot one line in different colors http://stackoverflow.com/questions/17240694/python-how-to-plot-one-line-in-different-colors this will be terribly slow to draw. In that case use a LineCollection . E.g. import numpy as np import matplotlib.pyplot as plt from.. as plt from matplotlib.collections import LineCollection xy np.random.random 1000 2 0.5 .cumsum axis 0 # Reshape things.. 1 2 segments np.hstack xy 1 xy 1 fig ax plt.subplots coll LineCollection segments cmap plt.cm.gist_ncar coll.set_array np.random.random..
matplotlib change linewidth on line segments, using list http://stackoverflow.com/questions/19862011/matplotlib-change-linewidth-on-line-segments-using-list this question Basically you have two options. Use a LineCollection . In this case your line widths will be in points and the line.. as plt from matplotlib.collections import LineCollection np.random.seed 1977 x np.arange 10 y np.cos x np.pi width 20.. start end for start end in zip coords 1 coords 1 lines LineCollection lines linewidths width fig ax plt.subplots ax.add_collection..
Set line colors according to colormap http://stackoverflow.com/questions/19868548/set-line-colors-according-to-colormap share improve this question It's easiest to use a LineCollection for this. In fact it expects the lines to be in a similar format.. as plt from matplotlib.collections import LineCollection # The line format you curently have lines 0 1 2 3 4 4 5 6 7.. 2 3 4 8 7 6 5 4 4 5 6 7 8 0 1 2 3 4 # Reformat it to what `LineCollection` expects lines zip x y for x y in lines z np.array 0.1 9.4 3.8..
