Matplotlib.axis.axis.get_units()

matplotlib库的Axis模块中的Axis.get_units()函数用于获取Axis的单位。

语法:Axis.get_units(self)

参数:该方法不接受任何参数。

返回值:该方法返回轴的单位。

下面的例子演示了matplotlib.axis.axis.get_units()函数在matplotlib.axis中的作用:

示例1

# Implementation of matplotlib function
from matplotlib.axis import Axis
import random
import matplotlib.lines as lines
import matplotlib.patches as patches
import matplotlib.text as text
import matplotlib.collections as collections
from basic_units import cm, inch
import numpy as np
import matplotlib.pyplot as plt
   
fig, ax = plt.subplots()
ax.xaxis.set_units(cm)
ax.yaxis.set_units(cm)
   
np.random.seed(19680801)
   
line = lines.Line2D([2*cm, 8*cm], [0*cm, 2.5*cm],
                    lw=2, color='green', axes=ax)
ax.add_line(line)
   
t = text.Text(3*cm, 2.5*cm, 
              'Line 1',
              ha='left',
              va='bottom',
              axes=ax,
              color='red')
ax.add_artist(t)
  
ax.grid(True)
  
print("Value return by get_units() :",
      ax.xaxis.get_units())
   
fig.suptitle("""matplotlib.axis.Axis.get_units()
function Example\n""", fontweight ="bold")  
       
plt.show()

输出:

Value return by get_units() : centimeters

示例2

# Implementation of matplotlib function
from matplotlib.axis import Axis
import numpy as np
import matplotlib.pyplot as plt
from basic_units import secs
   
# create masked array
data = (1, 2, 3, 4, 5, 6, 7, 8)
mask = (1, 0, 1, 0, 0, 0, 1, 0)
xsecs = secs * np.ma.MaskedArray(data, mask, float)
   
fig, ax1 = plt.subplots()
   
ax1.scatter(xsecs, xsecs)
ax1.yaxis.set_units(secs)
   
ax1.grid()
  
print("Value return by get_units() :",
      ax1.yaxis.get_units())
   
fig.suptitle("""matplotlib.axis.Axis.get_units()
function Example\n""", fontweight ="bold")  
       
plt.show()

输出:

Value return by get_units() : seconds
