import matplotlib
matplotlib.use('Agg') # Must be before importing matplotlib.pyplot or pylab!
import matplotlib.pyplot as plt
import numpy as np
fig = plt.figure()
x=np.linspace(0,10,100);
plt.plot(x,np.sin(x));
fig.hold();
x=np.linspace(0,10,100);
plt.plot(x,0.5*np.cos(2*x));
plt.title("A matplotlib plot");
plt.text(1,-0.8,"cos func");
plt.ylim(-1.1,1.1);
fig.savefig('temp.png')

運行： liuyu: ~/MyTars/epd_free-7.3-2-rh5-x86_64/bin/Workbench$ ../python2.7 a.py

2.的安裝參加http://blog.sina.com.cn/s/blog_61f013b80100yhef.html,我安裝的版本是 R-2.15.2

2安裝成功運行

 

3. 安裝的版本是gsl-1.9，安裝的位置是liuyu: ~/GSL4. 安裝完上述四個開源庫後我的.bashrc內容如下 

export PATH=$PATH:/home/liuyu/MyTars/epd_free-7.3-2-rh5-x86_64/bin                
export PATH=$PATH:/home/liuyu/MyTars/R-2.15.2/bin                                 
export R_HOME=/home/liuyu/MyTars/R-2.15.2/bin/R
export R_LIBS=/search/liuyu/MyTars/R-2.15.2/library
export LD_LIBRARY_PATH=${R_HOME}/lib:${LD_LIBRARY_PATH}
export LD_LIBRARY_PATH=/usr/local/lib:${LD_LIBRARY_PATH}  
export LD_LIBRARY_PATH=/home/liuyu/GSL/lib:${LD_LIBRARY_PATH} 

5. 源碼安裝軟體的方式

tar -xzvf source.tar.gz

cd source

./configure --prefix=dir//指定安裝目錄

make

make install

卸載 make uninstall

6.程式調用GSL庫（使用automake做編譯）

Makefile.am的內容

 include $(top_srcdir)/common.mk
 
 bin_PROGRAMS=
 lib_LIBRARIES=
  ib_LTLIBRARIES=
  
  bin_PROGRAMS+=test
  INCLUDES=-I /search/liuyu/GSL/include
  test_SOURCES=test.cpp                                                                                         
 test_LDADD=  /home/liuyu/GSL/lib/libgsl.so /home/liuyu/GSL/li
    b/libgslcblas.so 
 test_LDFLAGS=-static-libtool-libs

 運行結果：

 

 gnuplot安裝1. 下載wxGTK-2.8.12-i486-1alien.tgz，解壓後將libwx_gtk2u_richtext-2.8.so.0.8.0拷貝至/usr/local/lib(之所以放在這裡是因為/etc/ld.so.conf中指定了這個目錄為動態連結程式庫的功能目錄)2. 然後 進入源碼，以root身份安裝我的gnuplot源碼為gnuplot-4.6.rc1.tar.gz3. 之後配置bashrc中的path export PATH=$PATH:gnuplot的安裝目錄4.調用 檔案名稱plot.gp中有以下內容1 plot sin(x)                                                                                                                 
  2 set grid
  3 set xlabel "X"
  4 set ylabel "Y"
  5 set terminal png
  6 set output "plot.png"
  7 replotgnuplot plog.gp會在當前路徑下產生plot.png 

f=scan(file="f3.txt");

#png(file="myplot2.png", bg="transparent");
#boxplot(f);
fivenum(f);
