使用x轴上的标签(而不是计数)打印直方图matplotlib

找到了答案。

battles.attacker_1.value_counts().plot(kind = 'bar')

对于 香草matplotlib 解决方案,使用 xticklabels 具有 xticks :

import random
import matplotlib.pyplot as plt


NUM_FAMILIES = 10

# set the random seed (for reproducibility)
random.seed(42)

# setup the plot
fig, ax = plt.subplots()

# generate some random data
x = [random.randint(0, 5) for x in range(NUM_FAMILIES)]

# create the histogram
ax.hist(x, align='left') # `align='left'` is used to center the labels

# now, define the ticks (i.e. locations where the labels will be plotted)
xticks = [i for i in range(NUM_FAMILIES)]

# also define the labels we'll use (note this MUST have the same size as `xticks`!)
xtick_labels = ['Family-%d' % (f+1) for f in range(NUM_FAMILIES)]

# add the ticks and labels to the plot
ax.set_xticks(xticks)
ax.set_xticklabels(xtick_labels)

plt.show()

这将产生:

你可以看看 pandas plot

df.set_index('Family').Battles.plot(kind='bar')
