以下是实现这一功能的代码: importmatplotlib.pyplotasplt# 准备数据months=list(sales_data.keys())sales=list(sales_data.values())# 创建折线图plt.figure(figsize=(10,5))plt.plot(months,sales,marker='o',linestyle='-',color='b')plt.title('Monthly Sales Data')plt.xlabel('Months')plt.ylabel('...
fig.savefig('path/to/save/image/to.png') # save the figure to file plt.close(fig) # close the figure window 1. 2. 3. 4. 5. 如果需要用fig.show()的话,应该需要重开 figure(不过我没试过)。 Lukasz Czerwinski– vote: 172 解决: pylab.savefig('foo.png') 1. Save plot to image fil...
Here is an example Python code that creates theMatplitlibfigure, saves to a file, and loads it back: importpickleimportmatplotlib.pyplotasplt# create figurefig=plt.figure()plt.plot([4,2,3,1,5])# save whole figurepickle.dump(fig,open("figure.pickle","wb"))# load figure from filefig...
plt.close() plt.rc('text', usetex=False) fig = plt.figure(figsize=(4,5)) plt.plot(x, x*x,'ko') plt.title('Page Three') pdf.savefig(fig)# or you can pass a Figure object to pdf.savefigplt.close()# We can also set the file's metadata via the PdfPages object:d = pdf.in...
plt.savefig('file_name', format='jpg') 如果不指定format,默认为jpg格式,与文件的后缀名无关 1.1.4 设置图像dpi 代码语言:txt AI代码解释 plt.savefig(..., dpi=150) 1.1.5 直接获取bin图像流 在服务器环境,或者特定环境下,我们不建议用文件来交换画图结果,更希望函数直接返回一个二进制的图像文件。
或者使用 mpimg.pil_to_array(pilImage),将 PIL 对象转换成矩阵 也可以使用 plt.matshow(A, fignum = None, **kwargs),与 imshow 的区别在于,A 只能是一个灰度的矩阵,参数和 imshow 的基本相同,fignum 定义了使用的 figure(画布): None 即新打开一个画布 ...
import matplotlib.pyplot as plt fig, ax = plt.subplots( nrows=1, ncols=1 ) # create figure & 1 axis ax.plot([0,1,2], [10,20,3]) fig.savefig('path/to/save/image/to.png') # save the figure to file plt.close(fig) # close the figure window 如果需要,您应该可以稍后重新打开...
