How to set color in matplotlib histograms

I am plotting a histogram using Matplotlib. I would like the color of the histogram to be "sky blue". But the data overlaps, and produces a histogram which is nearly black in color.

plt.hist(data, color = "skyblue")

Below is how the histogram looks. As you can see, even though I specified the color to be "Skyblue, the histogram on the right is nearly black.

Solution

  • The reason for the histogram to look black is that the bars' surrounding lines (which are black) take most of the space.

    Options would be to get rid of the edges by setting the linewidth to zero:

    plt.hist(data, color = "skyblue", lw=0)

    and/or to set the edgecolor to the same color as the bars itself

    plt.hist(data, color = "skyblue", ec="skyblue")
