Python Matplotlib.axis.Axis.get_units()用法及代碼示例

Matplotlib是Python中的一個庫,它是數字的-NumPy庫的數學擴展。它是Python中令人驚歎的可視化庫,用於數組的2D圖,並用於與更廣泛的SciPy堆棧配合使用。

Matplotlib.axis.Axis.get_units()函數

matplotlib庫的軸模塊中的Axis.get_units()函數用於獲取軸的單位。

用法: Axis.get_units(self) 

參數:此方法不接受任何參數。

返回值:此方法返回軸的單位。



以下示例說明了matplotlib.axis中的matplotlib.axis.Axis.get_units()函數:
範例1:

Python3

# 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()

輸出:

Value return by get_units():centimeters

範例2:

Python3

# 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()

輸出:

Value return by get_units():seconds
