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：
  ^9 R3 z9 A) T* `( r, wShadePlotForEmpahsis
1 Z9 P) \: \+ W$ }/ Q4 |* |# d: `  Plots a shaded bar for emphasis as commonly seen on cconomic charts

  INPUTS:
3 I4 I2 g, y; U7 K: b& W4 J   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}
4 n! P7 u/ a; S, q, J% }! w" `4 ]; \, K  colors Use 'y' to make all bars yellow.  Use {'y','g','r'} for
& _  r, W5 W7 a, o         yellow, green and red bars.
  alphas Use 0.5 if you want all bars to be translucent.  Use {0,.5,1}
7 ]) \1 K% H9 `4 s/ x( ~         for transparent, translucet and opaque bars.
