Matlab高亮显示部分数据

ulppknot

有的时候你需要把你的一部分数据重点显示给读者，如何高亮显示这部分数据呢。Matlab（至少2010版)里面提供了一个ShadePlotForEmpahsis函数，help ShadePlotForEmpahsis会提供如下帮助：
8 n0 I) K" x5 ~; h- r$ {" |ShadePlotForEmpahsis
" {7 A1 K4 q: Q! z7 U; ]  Plots a shaded bar for emphasis as commonly seen on cconomic charts
" @/ E$ K* ]5 z1 `/ m, b! K; j
  INPUTS:
( m3 e+ v' Y; W3 l% `   x     where the bar is placed.   If you want a bar from x=4:8 then
         use [4 8].  If you want x=[4:8,10:20] then use {4:8,10:20}
  colors Use 'y' to make all bars yellow.  Use {'y','g','r'} for
         yellow, green and red bars.
0 e; t% Q5 n3 s7 y& ]  alphas Use 0.5 if you want all bars to be translucent.  Use {0,.5,1}
% d( w& V) G) s0 d5 i% E  ]& b         for transparent, translucet and opaque bars.
