Matlab高亮显示部分数据

uqHZau

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：
% A: f' G6 @2 F' ]% k5 G7 i. z3 ]ShadePlotForEmpahsis
, R/ W0 i. `7 J  Plots a shaded bar for emphasis as commonly seen on cconomic charts

  INPUTS:
9 C. F; q5 [- O6 U9 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.
6 g( W. J- L* Y+ e! A) }% [5 C  alphas Use 0.5 if you want all bars to be translucent.  Use {0,.5,1}
         for transparent, translucet and opaque bars.
