根据数据框制作2个变量的条形图

Question

I am trying to plot a graph of two variables but without success. My goal is to to create a bar graph where the Events1 And Events2 appear along in order to be easier to compare the "Name" (two bars for each Name). My code below generates two graphs wrongly. Can you point me out to the correct way of doing this?Thanks.

My df is:

         Name  Events1 Events2
0  Accounting        3       3
1   Reporting        1       4
2     Finance        1      13
3       Audit        1      17
4    Template        2      40

Code:

import matplotlib.pyplot as plt
ax = df[['Events1','Events2']].plot(kind='bar', title ="test", figsize=(15, 10), legend=True, fontsize=12)
ax.set_xlabel("Name", fontsize=12)
ax.set_ylabel("Number", fontsize=12)
plt.show()

Answer 1

Use set_index

In [3596]: df.set_index('Name').plot.bar()
Out[3596]: <matplotlib.axes._subplots.AxesSubplot at 0x2954d208>

---

In [3595]: df.set_index('Name')
Out[3595]:
            Events1  Events2
Name
Accounting        3        3
Reporting         1        4
Finance           1       13
Audit             1       17
Template          2       40

Answer 2

You can simply pass two Y-axis values

df.plot.bar(x = 'Name', y = ['Events1', 'Events2'], rot = 40)

If you wish to annotate the bars, try

fig, ax = plt.subplots()
df.plot.bar(x = 'Name', y = ['Events1', 'Events2'], rot = 40, ax = ax)
for p in ax.patches: 
    ax.annotate(np.round(p.get_height(),decimals=2), (p.get_x()+p.get_width()/2., p.get_height()))
