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：
ShadePlotForEmpahsis
2 B! J/ I% m( p, K# Z0 x' B6 F  Plots a shaded bar for emphasis as commonly seen on cconomic charts

  INPUTS:
* @, v! `* m0 ^2 E  @8 S  u   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.
  alphas Use 0.5 if you want all bars to be translucent.  Use {0,.5,1}
) I( A' @6 i; N- d, `/ Z         for transparent, translucet and opaque bars.
