I am trying to plot groups of data which have different bar sizes and may have different group sizes. How can I group the bars that belong to the same groups (shown as the same color) so that they are side by side? (Similar to this , except the same colors should be side-by-side)
width = 0.50
groupgap=2
y1=[20,80]
y2=[60,30,10]
x1 = np.arange(len(y1))
x2 = np.arange(len(y2))+groupgap
ind = np.concatenate((x1,x2))
fig, ax = plt.subplots()
rects1 = ax.bar(x1, y1, width, color='r', ecolor= "black",label="Gender")
rects2 = ax.bar(x2, y2, width, color='b', ecolor= "black",label="Type")
ax.set_ylabel('Population',fontsize=14)
ax.set_xticks(ind)
ax.set_xticklabels(('Male', 'Female','Student', 'Faculty','Others'),fontsize=14)
ax.legend()
The idea of using a gap between the categories ( groupgap
) is indeed a way to go. You would just have to add the length of the first group as well:
x2 = np.arange(len(y2))+groupgap+len(y1)
Here is the complete example where I used groupgap=1
:
import matplotlib.pyplot as plt
import numpy as np
width = 1
groupgap=1
y1=[20,80]
y2=[60,30,10]
x1 = np.arange(len(y1))
x2 = np.arange(len(y2))+groupgap+len(y1)
ind = np.concatenate((x1,x2))
fig, ax = plt.subplots()
rects1 = ax.bar(x1, y1, width, color='r', edgecolor= "black",label="Gender")
rects2 = ax.bar(x2, y2, width, color='b', edgecolor= "black",label="Type")
ax.set_ylabel('Population',fontsize=14)
ax.set_xticks(ind)
ax.set_xticklabels(('Male', 'Female','Student', 'Faculty','Others'),fontsize=14)
plt.show()
