Yesterday I wrote a small PowerShell script, that makes use of the Google Chart API. I thought It might be of interest to others:

function simpleEncoding ($valueArray, $labelArray, $size, [switch] $chart3D) { $simpleEncoding = 'ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz0123456789' if ($chart3D) {$chartType = "p3"} else {$chartType ="p"} $total = 0 foreach ($value in $valueArray) { $total = $total + $value } for ($i = 0;$i -lt $valueArray.length;$i++) { $relativeValue = ($valueArray[$i] / $total)*62 $relativeValue = [math]::round($relativeValue) $encodingValue = $simpleEncoding[$relativeValue] $chartData = $chartData + "" + $encodingValue } $chartLabel = [string]::join("|",$labelArray) Write-Output "http://chart.apis.google.com/chart?cht= $chartType&chd=s:$chartdata&chs=$size&chl=$chartLabel" }

function DownloadAndShowImage ($url) { $localfilename = ".\chart.png" $webClient = new-object System.Net.WebClient $webClient.Headers.Add("user-agent", "PowerShell Badass Script v666") $Webclient.DownloadFile($url, $localfilename) Invoke-Item $localfilename }

$values = 100,11,40,9 $text = "Hans","Jane","Rose","Simon" $url = simpleEncoding $values $text "320x150" -Chart3D DownloadAndShowImage $url
