Matplotlib Errorbar Plot - Using A Custom Colormap

I'm trying to make an errorbar plot with different colors for each point along the x axis. The errorbar chart itself is coming out fine, but it bombs when I try to use a colormap,

Solution 1:

I already mentioned that you can loop over each particular point/color.

Another solution is to use a scatter plot within your errorbar plot, like in this question. The code is below

import matplotlib.pyplot as pltcolors= ["b","g","c","m","y","k","r","g","c","m","y","k",
          "b","g","c","m","y","k","r","g","c","m","y","k"]

xlabels = ['A','B','8','14']

xval = [0, 1, 2, 3]
yval = [0, 1, 4, 9]
yerr = [0.5, 0.4, 0.6, 0.9]

plt.scatter(xval, yval, c=colors, s=50, zorder=3)
plt.errorbar(xval, yval, yerr=yerr, zorder=0, fmt="none",
             marker="none")

plt.savefig("scatter_error.png", dpi=300)
plt.show()

With the following result
