# To show the difference between 4 bit color and 8 bit color *if your console supports VT ANSI commands and 8 bit color*

PS> Get-Sparkline $n -NumLines 3 -Emphasis @(
    New-Empahsis -Color 55 -Predicate { param($x) $x -like '5*' } # 55 is like a dark magenta
    New-Emphasis -Color 'Red' -Predicate { param($x) $x -gt 50 }

Emphasis

As shown above, the first Emphasis object that has a true predicate will determine the color of the spark index.

Why?

This is just a quick little module to help visualize sparklines in the command-line. It is explained better in the sparklines repo. The Wikipedia entry also offers insight.
