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：
/ |0 ~9 t0 F2 X. @' G2 U* z# PShadePlotForEmpahsis
  Plots a shaded bar for emphasis as commonly seen on cconomic charts

& V) ~# B, o/ f! Y  INPUTS:
   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}
) V: q& ?! ]" g. t. f. e$ m  colors Use 'y' to make all bars yellow.  Use {'y','g','r'} for
) F; y+ H+ M0 H; j         yellow, green and red bars.
2 d7 h! P5 J* S* B8 U+ M  alphas Use 0.5 if you want all bars to be translucent.  Use {0,.5,1}
# @2 ~( R* R& N; [( h         for transparent, translucet and opaque bars.
