Python matplotlib绘图不显示

我将PythonV3.6与pycharm和anaconda一起使用。我试着运行下面的代码来绘制一个简单的正弦波

import numpy as np
import matplotlib.pyplot as plt

# Generate a sequence of numbers from -10 to 10 with 100 steps in between
x = np.linspace(-10, 10, 100)
# Create a second array using sine
y = np.sin(x)
# The plot function makes a line chart of one array against another
plt.plot(x, y, marker="x")
pass

---

代码运行平稳，没有错误，但没有显示绘图。如何使绘图显示？

最后缺少

plt.show（）

import numpy as np
import matplotlib.pyplot as plt

# Generate a sequence of numbers from -10 to 10 with 100 steps in between
x = np.linspace(-10, 10, 100)
# Create a second array using sine
y = np.sin(x)
# The plot function makes a line chart of one array against another
plt.plot(x, y, marker="x")
plt.show()
pass

或者，如果要将其保存到文件中

plt.savefig("my_file.png")
