fortran 调用 gnuplot

fortran 调用 gnuplot

同时参考 彭国伦 绘图

1.下载并安装gnuplot（http://gnuplot.info/），安装路径为d:/gnuplot；
2.下载ogpf-0.12（http://mfort.codeplex.com/）。
3.新建console工程，加入ogpf-0.12解压缩后其中的demo.f90和ogpf.f90.编译，观察结果。

如果提示编译错误，请注意：
打开ogpf.f90，将其中的一段代码改为下面的代码：

IF (Persist) THEN
!Fortran standard recommend to use call execute_command_line to invoke another program
!from within Fortran, the old method was to use call system
!Here by default Fortran standard is used, if you have a compiler does not support
!call execute_command_line, uncomment the following call system
!CALL system('gnuplot -persist '//fileName) !Obsolete method, use with old compilers
CALL system('d:/gnuplot/bin/gnuplot -persist '//fileName) !Fortran standard
ELSE
!CALL system ('gnuplot '//fileName) !Obsolete method, use with old compilers
CALL system ('d:/gnuplot/bin/gnuplot '//fileName)
END IF

 

重新编译即可！


效果：
