将多个绘图保存在一个 PDF 文件中

本文介绍了将多个绘图保存在一个 PDF 文件中的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！ 问题描述 def plotGraph(X,Y): fignum = random.randint(0,sys.maxint) plt.figure(fignum) ### Plotting arrangements ### return fignum

主模块

import matplotlib.pyplot as plt ### tempDLStats, tempDLlabels are the argument plot1 = plotGraph(tempDLstats, tempDLlabels) plot2 = plotGraph(tempDLstats_1, tempDLlabels_1) plot3 = plotGraph(tempDLstats_2, tempDLlabels_2) plt.show()

我想将所有图形 plot1、plot2、plot3 保存到一个 PDF 文件中.有什么方法可以实现吗?我无法在主模块中包含 plotGraph 函数.

I want to save all the graphs plot1, plot2, plot3 to a single PDF file. Is there any way to achieve it? I can't include the plotGraph function in the main module.

有一个名为 pyplot.savefig 的函数，但它似乎只适用于单个图形.还有其他方法可以实现吗?

There's a function named pyplot.savefig but that seems to work only with a single figure. Is there any other way to accomplish it?

推荐答案

没关系有办法去做.

def plotGraph(X,Y): fignum = random.randint(0,sys.maxint) fig = plt.figure(fignum) ### Plotting arrangements ### return fig
