matplotlib xticks标签重叠

我无法使用以下代码在Xtick之间获得更好的空格：

import random
import matplotlib.pyplot as plt

coverages = [random.randint(1,10)*2] * 100
contig_names = ['AAB0008r'] * len(coverages)
fig = plt.figure()
fig.clf()
ax = fig.add_subplot(111)

ax.yaxis.grid(True, linestyle='-', which='major', color='grey', alpha=0.5)

ind = range(len(coverages))
rects = ax.bar(ind, coverages, width=0.2, align='center', color='thistle')
ax.set_xticks(ind)
ax.set_xticklabels(contig_names)
#function to auto-rotate the x axis labels
fig.autofmt_xdate()

plt.show()

如何在XTick之间获得更多空间，使它们看起来不再重叠

提前谢谢。

您可以尝试更改体形大小、Xticklabel的大小、旋转角度等

# Set the figure size
fig = plt.figure(1, [20, 8])

# Set the x-axis limit
ax.set_xlim(-1,100)
# Change of fontsize and angle of xticklabels
plt.setp(ax.get_xticklabels(), fontsize=10, rotation='vertical')
