Matlab高亮显示部分数据

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
  Plots a shaded bar for emphasis as commonly seen on cconomic charts
# \5 ~3 M# A9 J
  INPUTS:
/ j' }% d, X8 P   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}
/ G1 Q3 ?1 F4 ^8 D" b1 g5 P  colors Use 'y' to make all bars yellow.  Use {'y','g','r'} for
' H" j* S, E1 ]* e0 d5 f         yellow, green and red bars.
