Let’s see an example where we save the plot with dpi: # Import Libraryimport matplotlib.pyplot as plt import numpy as np# Define Datax = np.arange(0, 12, 0.2) y = np.sin(x)# Plot figureplt.plot(x, y)# Save as pdfplt.savefig('save as dpi .pdf', dpi=120, format='pdf', ...
# plt.grid(True)plt.grid(axis='y')# Legendforthe plot.plt.legend()# Saving the figure on disk.'dpi'and'quality'can be adjusted according to the required image quality.plt.savefig('Bar_plot.jpeg',dpi=400,quality=100)# Displays the plot.plt.show()# Clears the current figure contents....

The extent can change due to any changes in the transform stack, such as changing the axes limits, the figure size, or the canvas used (as is done when saving a figure). This can lead to unexpected behavior where interactive figures will look fine on the screen, but will save ...
我需要拍摄图像并经过一些处理将其保存。显示该图形时,它看起来不错,但是保存该图形后,在保存的图像周围有一些空白。我尝试过方法的'tight'选项savefig,也没有用。编码: import matplotlib.image as mpimg import matplotlib.pyplot as plt fig = plt.figure(1) ...
Matplotlib在绘制Figure对象时,允许用户确定图像纵横比、图像精度和大小,采用figsize和dpi关键字参数。figsize是关于图像宽度和高度(单位:英寸)的元组型变量,dpi是每英寸点数(像素)。为创建一个800×400像素,每英寸点数为100的图像,代码如下: In [14]: fig = plt.figure(figsize=(8,4), dpi=100) <matplotlib.fi...
