#253 Control the color in stacked area chart

Once you understand how to create a stacked area chart and which baseline option to choose, it’s highly recommended to custom the colors of your chart. Here I propose 2 solutions: the first consists to use a common color palette, the second allows you to pick up your colors one by one.


# library
import numpy as np
import matplotlib.pyplot as plt
import seaborn as sns

# Your x and y axis
x=range(1,6)
y=[ [10,4,6,5,3], [12,2,7,10,1], [8,18,5,7,6] ]

# use a known color palette (see..)
pal = sns.color_palette("Set1")
plt.stackplot(x,y, labels=['A','B','C'], colors=pal, alpha=0.4 )
plt.legend(loc='upper right')
plt.show()

# create your palette
pal = ["#9b59b6", "#e74c3c", "#34495e", "#2ecc71"]
plt.stackplot(x,y, labels=['A','B','C'], colors=pal, alpha=0.4 )
plt.legend(loc='upper right')
