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_figure()函數
matplotlib庫的axis模塊中的Axis.get_figure()函數用於獲取藝術家所屬的Figure實例。
用法: Axis.get_figure(self)
參數:此方法不接受任何參數。
返回值:此方法返回藝術家所屬的Figure實例。
以下示例說明了matplotlib.axis中的matplotlib.axis.Axis.get_figure()函數:
範例1:
Python3
# Implementation of matplotlib function
from matplotlib.axis import Axis
import numpy as np
import matplotlib.pyplot as plt
import matplotlib.lines as lines
import matplotlib.transforms as mtransforms
import matplotlib.text as mtext
class GFGfun(lines.Line2D):
def __init__(self, *args, **kwargs):
self.text = mtext.Text(0, 0, '')
lines.Line2D.__init__(self, *args, **kwargs)
self.text.set_text(self.get_label())
def set_figure(self, figure):
self.text.set_figure(figure)
lines.Line2D.set_figure(self, figure)
def set_axes(self, axes):
self.text.set_axes(axes)
lines.Line2D.set_axes(self, axes)
def set_transform(self, transform):
# 2 pixel offset
texttrans = transform + mtransforms.Affine2D().translate(2, 2)
self.text.set_transform(texttrans)
lines.Line2D.set_transform(self, transform)
def set_data(self, x, y):
if len(x):
self.text.set_position((x[-1], y[-1]))
lines.Line2D.set_data(self, x, y)
def draw(self, renderer):
lines.Line2D.draw(self, renderer)
self.text.draw(renderer)
np.random.seed(10**7)
fig, ax = plt.subplots()
x, y = np.random.rand(2, 20)
line = GFGfun(x, y, mfc ='green',
ms = 12,
label ='Label')
line.text.set_color('green')
line.text.set_fontsize(16)
ax.add_line(line)
ax.text(0.2, 0.8, "Value Return:"
+str(Axis.get_figure(ax)),
fontweight ="bold")
fig.suptitle("""matplotlib.axis.Axis.get_figure()
function Example\n""", fontweight ="bold")
plt.show()
