Matplotlib.axes.Axes.redraw_in_frame() in Python
Matplotlib is a library in Python and it is numerical – mathematical extension for NumPy library. The Axes Class contains most of the figure elements: Axis, Tick, Line2D, Text, Polygon, etc., and sets the coordinate system. And the instances of Axes supports callbacks through a callbacks attribute.
matplotlib.axes.Axes.redraw_in_frame() Function
The Axes.redraw_in_frame() function in axes module of matplotlib library is used to efficiently update Axes data.
Syntax: Axes.redraw_in_frame(self)
Parameters: This method does not accepts any parameters.
Returns: This method does not return any value.
Note: This method can only be used after an initial draw which caches the renderer.
Below examples illustrate the matplotlib.axes.Axes.redraw_in_frame() function in matplotlib.axes:
Example 1:
import matplotlib.pyplot as plt
fig, ax = plt.subplots()
def tellme(s):
ax.set_title(s, fontsize = 12 , fontweight = "bold" )
fig.canvas.draw()
ax.redraw_in_frame()
tellme('matplotlib.axes.Axes.redraw_in_frame() function \
Example')
plt.show()
|
Output:
Example 2:
import matplotlib.pyplot as plt
import numpy as np
import time
fig, ax = plt.subplots()
line, = ax.plot(np.random.randn( 100 ))
tstart = time.time()
num_plots = 0
fig.canvas.draw()
while time.time() - tstart < 5 :
line.set_ydata(np.random.randn( 100 ))
ax.redraw_in_frame()
num_plots + = 1
ax.set_title('matplotlib.axes.Axes.redraw_in_frame() \
function Example')
plt.show()
