gnuplot 画图

写的一个scripts，2D figure

在windows版本下的gnuplot版本terminal 是windows
在linux版本下的gnuplot版本terminal 是 wxt

首先将mat数据，用dlmwrite转成文本形式。x，y,分别各为1列，'MODRPaC' 和 'PCA' 各为一列。

3D figure:

set xrange [0:1]
set yrange [0:1]
set ticslevel 0
set dgrid3d 30,30
set hidden3d
splot "./mesh_digit.txt" u 1:2:3 w l t 'MODRPaC', '' u 1:2:4 w l t 'PCA'
