英文:
Histogram of integer values with correct x-axis ticks and labels
问题
以下是您要翻译的代码部分：
import numpy as npimport matplotlib.pyplot as plt# 生成整数值n = 20values = np.random.randint(low=0, high=(n+1), size=1000)# 绘制直方图fig, ax = plt.subplots(figsize=(20, 4))_, bins, _ = ax.hist(values, bins=n+1, edgecolor='k', color='lightsalmon')ax.set_xticks(bins)ax.set_xticklabels(bins.astype(int))plt.show()
如果您需要进一步的帮助，请随时提出。
英文:
I have integer values from 0 to n (included) and I would like to plot a histogram with n+1 bars at with the correct x-axis labels. Here is my attempt.
import numpy as npimport matplotlib.pyplot as plt# Generate integer valuesn = 20values = np.random.randint(low=0, high=(n+1), size=1000)# Plot histogramfig, ax = plt.subplots(figsize=(20, 4))_, bins, _ = ax.hist(values, bins=n+1, edgecolor='k', color='lightsalmon')ax.set_xticks(bins)ax.set_xticklabels(bins.astype(int))plt.show()
It is almost correct, but the x-axis looks weird.

这应该可以完成任务。
import numpy as npimport matplotlib.pyplot as plt# 生成整数值n = 20values = np.random.randint(low=0, high=(n+1), size=1000)# 绘制直方图fig, ax = plt.subplots(figsize=(20, 4))bins = np.arange(start=-0.5, stop=(n+1), step=1)_ = ax.hist(values, bins=bins, edgecolor='k', color='lightsalmon')ax.set_xticks(np.arange(n+1))plt.show()
英文:
This should do the job.
