Out-AnsiGraph

Inspired by Chad Miller’s work MSChart I threw this ANSI barchart module together:

function Out-AnsiGraph($Parameter1=$null) {
	BEGIN {
		$q = new-object Collections.queue
		$max = 0; $namewidth = 0;
	}

	PROCESS {
		if($_) {
			$name = $_.($Parameter1[0]);
			$val = $_.($Parameter1[1])
			if($max -lt $val) { $max = $val}		 
			if($namewidth -lt $name.length) { 
				$namewidth = $name.length }
			$q.enqueue(@($name, $val))			
		}
	}

	END {
		$q | %{
			$graph = ""; 0..($_[1]/$max*20) | 
				%{ $graph += "█" }
			$name = "{0,$namewidth}" -f $_[0]
			"$name $graph " + $_[1]
		}

	}
}
