函數(shù)功能：
Set a property on an artist object.
設(shè)置元素屬性
函數(shù)語法：
setp(obj, *args, **kwargs)

函數(shù)參數(shù)：
obj： 要設(shè)置的對象

matplotlib supports the use of setp() (“set property”) and getp() to set and get object properties, as well as to do introspection on the object.
matplotlib 支持使用setp()函數(shù)設(shè)置屬性，使用getp（）函數(shù)獲取查看屬性，以及進行自查。

例如要將線條風(fēng)格設(shè)置為虛線，可以：

line, = plot([1,2,3]) setp(line, linestyle='--') import matplotlib.pyplot as plt import numpy as npx = np.linspace(-2*np.pi, 2 * np.pi, 200) y = np.sin(x)line1,=plt.plot(x,y)plt.setp(line1,ls='--')plt.show()

If you want to know the valid types of arguments, you can provide the name of the property you want to set without a value:
如果您想知道參數(shù)有效的類型（可取的值），則可以提供要設(shè)置的屬性名稱，但不帶值。

setp(line, 'linestyle')

例如：獲取線條風(fēng)格的取值有哪些

import matplotlib.pyplot as plt import numpy as npx = np.linspace(-2*np.pi, 2 * np.pi, 200) y = np.sin(x)line,=plt.plot(x,y)plt.setp(line,'linestyle')

3. If you want to see all the properties that can be set, and their possible values, you can do:
如果你想要查看所有可以設(shè)置的屬性和屬性的取值，可以：

setp(line) import matplotlib.pyplot as plt import numpy as npx = np.linspace(-2*np.pi, 2 * np.pi, 200) y = np.sin(x)line1,=plt.plot(x,y)plt.setp(line1)
