PLOT AXIS RANGE HIGHLIGHTS

做一个高亮范围

我们可以利用高亮区域来给我们后面的作图加上底板，比如scatter plot

<highlight>
file       = data/3/chr.highlights.colourless.txt
r0 = 0.715r
r1 = 0.725r
fill_color = lred
</highlight>

<highlight>
file       = data/3/chr.highlights.colourless.txt
r0 = 0.725r
r1 = 0.75r
fill_color = lorange
</highlight>

<highlight>
file       = data/3/chr.highlights.colourless.txt
r0 = 0.75r
r1 = 0.80r
fill_color = lyellow
</highlight>
