[Matplotlib-users] changing the shade of a color depending on a value
Hi, I am currently plotting cpu utilization over time (plot_time). I would like the color of my line to be red when at 100%. 80-90% a bit less red, more yellow, and lower numbers will be green. Any thoughts of doing this? -- --- Get your facts first, then you can distort them as you please.-- -- Everyone hates slow websites. So do we.

Joe Kington's answer is the best solution I've seen to this problem: http://stackoverflow.com/questions/13622909/matplotlib-how-to-colorize-a-large-number-of-line-segments-as-independent-gradi There is also an example in the gallery: http://matplotlib.org/examples/pylab_examples/multicolored_line.html HTH On 27 February 2013 09:49, Rita rmorgan...@gmail.com wrote: Hi, I am currently plotting cpu utilization over time (plot_time).

Hi have a look at http://matplotlib.org/examples/pylab_examples/multicolored_line.html and http://matplotlib.org/examples/pylab_examples/show_colormaps.html. br Jakob On 02/27/2013 10:49 AM, Rita wrote: Hi, I am currently plotting cpu utilization over time (plot_time).

A few years ago, Gökhan Sever posted this technique, which is the simplest and best I've seen: ## import numpy as np import matplotlib.pyplot as plt import matplotlib.cm as cm x = np.linspace(0, 3 * np.pi, 5000) y = np.sin(x) z = np.cos(0.5 * (x[:-1] + x[1:])) # 1st derivative cmap_z = cm.coolwarm(z) fig, ax1 = plt.subplots(nrows=1, ncols=1) ax1.scatter(x, y, c=cmap_z, marker='_', s=5) fig.show() ## -- Everyone hates slow websites.
