使用 matplotlib 将绘图保存为 pdf 文件 [英] Saving plots to pdf files using matplotlib

问题描述

我想将 1 个以上的绘图保存到 pdf 文件中.这是我的代码:

I want to save more than 1 plot to a pdf file. Here is my code:

import matplotlib.pyplot as plt
from matplotlib.backends.backend_pdf import PdfPages

def function_plot(X,Y):
    plt.figure()
    plt.clf()

    pp = PdfPages('test.pdf')

    graph = plt.title('y vs x')
    plt.xlabel('x axis', fontsize = 13)
    plt.ylabel('y axis', fontsize = 13)
    pp.savefig(graph)


function_plot(x1,y1)
function_plot(x2,y2)

我知道我的想法很混乱，但我找不到编写代码的方法.问题是我需要在图形上标注x和y轴.

I know that my ideas are scrambled but I can't find the way to write my code. The thing is that I need my graphs to have labeled x and y axis.

推荐答案

我能够解决它.我的错误是 pp.savefig()不应带有参数.

I was able to solve it. My mistake was that pp.savefig() should not take arguments.

这是我的最终代码:

from matplotlib.backends.backend_pdf import PdfPages
import numpy as np
import matplotlib.pyplot as plt

x1 = np.arange(10)
y1 = x1**2

x2 = np.arange(20)
y2 = x2**2

pp = PdfPages('test.pdf')


def function_plot(X,Y):
    plt.figure()
    plt.clf()

    plt.plot(X,Y)
    plt.title('y vs x')
    plt.xlabel('x axis', fontsize = 13)
    plt.ylabel('y axis', fontsize = 13)
    pp.savefig()

function_plot(x1,y1)
function_plot(x2,y2)

pp.close()
