  最近需要将实验数据画图出来,由于使用python进行实验,自然使用到了matplotlib来作图。

  下面的代码可以作为画图的模板代码,代码中有详细注释,可根据需要进行更改。

  

 1 # -*- coding: utf-8 -*- 2 import numpy as np 3 import matplotlib.pyplot as plt 4 plt.rcParams['font.sans-serif']=['Arial']   #如果要显示中文字体,则在此处设为:SimHei 5 plt.rcParams['axes.unicode_minus']=False    #显示负号 6  7 x = np.array([3,5,7,9,11,13,15,17,19,21]) 8 A = np.array([0.9708, 0.6429, 1, 0.8333, 0.8841, 0.5867, 0.9352, 0.8000, 0.9359, 0.9405]) 9 B= np.array([0.9708, 0.6558, 1, 0.8095, 0.8913, 0.5950, 0.9352, 0.8000, 0.9359, 0.9419])10 C=np.array([0.9657, 0.6688, 0.9855, 0.7881, 0.8667, 0.5952, 0.9361, 0.7848, 0.9244, 0.9221])11 D=np.array([0.9664, 0.6701, 0.9884, 0.7929, 0.8790, 0.6072, 0.9352, 0.7920, 0.9170, 0.9254])12 13 #label在图示(legend)中显示。若为数学公式,则最好在字符串前后添加"$"符号14 #color:b:blue、g:green、r:red、c:cyan、m:magenta、y:yellow、k:black、w:white、、、15 #线型:-    --     -.    :       , 16 #marker:.    ,      o      v        

  下面是上面代码绘制的图例:

 

  建议保存图片的格式svg(因为matplotlib存为eps矢量图时候会有问题),然后使用inkscape软件将svg格式转为emf矢量图格式。如果svg图片很多,可以在windows下使用批处理(安装inkscape软件后要记得设置path路径),下面这段代码能将它所在目录下的svg文件转为emf文件。将下面代码复制到文本文件,改后缀名为bat。

  

1 @echo off2 for %%i in (*.svg) do (3     echo %%i4     inkscape -f %%i -M %%~ni.emf5 )6 @echo Finished

mPDF

mPDF

mPDF is a PHP library that can generate PDF files from UTF-8 encoded HTML. The original author, Ian Back, wrote mPDF to output PDF files "on the fly" from his website and handle different languages. It is slower than original scripts like HTML2FPDF and produces larger files when using Unicode fonts, but supports CSS styles etc. and has a lot of enhancements. Supports almost all languages, including RTL (Arabic and Hebrew) and CJK (Chinese, Japanese and Korean). Supports nested block-level elements (such as P, DIV),
