# Show-Graph Consumes datapoints and draws colored coded fully customizable graph in the PowerShell console. - **Hashtags** UserCmdlet - **Version** 2019.10.01 #> using namespace System.Management.Automation function Show-Graph { <# .SYNOPSIS Draws graph in the PowerShell console .DESCRIPTION Consumes datapoints and draws colored coded fully customizable graph in the PowerShell console. .PARAMETER Datapoints Array of data points which is to be plotted on the graph .PARAMETER XAxisTitle Label on the X-Axis .PARAMETER YAxisTitle Label on the Y-Axis .EXAMPLE #$Datapoints = (1..100 | Get-Random -Count 100) #$Datapoints = 1..100 | % { Get-WmiObject -Class win32_processor | Select-Object -ExpandProperty LoadPercentage } #Show-Graph -Datapoints $Datapoints -XAxisTitle "Avg. CPU utilization" -YAxisTitle "Percentage" .NOTES Blog: https://geekeefy.wordpress.com/ Author: https://twitter.com/SinghPrateik Features and Benefits: * Color-coded output depending upon the Value of Datapoint * Custom X an Y-Axis labels * Graph in console is independent and fully customizable, not like Task Manager (Performance Tab) * Could be incorporated in PowerShell scripts * Can consume datapoints generated during script run or Pre stored data like in a file or database. #> [CmdletBinding()] Param( # Parameter help description [Parameter(Mandatory=$true)] [int[]] $Datapoints, [String] $XAxisTitle = 'X-Axis', [String] $YAxisTitle = 'Y Axis' ) $NumOfDatapoints = $Datapoints.Count $NumOfLabelsOnYAxis = 10 $XAxis = " "+"-"*($NumOfDatapoints+3) $YAxisTitleAlphabetCounter = 0 $YAxisTitleStartIdx = 1 $YAxisTitleEndIdx = $YAxisTitleStartIdx + $YAxisTitle.Length -1 If($YAxisTitle.Length -gt $NumOfLabelsOnYAxis){ Write-Warning "No. Alphabets in YAxisTitle [$($YAxisTitle.Length)] can't be greator than no. of Labels on Y-Axis [$NumOfLabelsOnYAxis]" Write-Warning "YAxisTitle will be cropped" } If($XAxisTitle.Length -gt $XAxis.length-3){ $XAxisLabel = " "+$XAxisTitle }else{ $XAxisLabel = " "+(" "*(($XAxis.Length - $XAxisTitle.Length)/2))+$XAxisTitle } # Create a 2D Array to save datapoints in a 2D format $Array = New-Object 'object[,]' ($NumOfLabelsOnYAxis+1),$NumOfDatapoints $Count = 0 $Datapoints | ForEach-Object { $r = [Math]::Floor($_/10) $Array[$r,$Count] = [char] 9608 1..$R | ForEach-Object {$Array[$_,$Count] = [char] 9608} $Count++ } # Draw graph For($i=10;$i -gt 0;$i--){ $Row = '' For($j=0;$j -lt $NumOfDatapoints;$j++){ $Cell = $Array[$i,$j] $String = If([String]::IsNullOrWhiteSpace($Cell)){' '}else{$Cell} $Row = [string]::Concat($Row,$String) } $YAxisLabel = $i*10 # Condition to fix the spacing issue of a 3 digit vs 2 digit number [like 100 vs 90] on the Y-Axis If("$YAxisLabel".length -lt 3){$YAxisLabel = (" "*(3-("$YAxisLabel".length)))+$YAxisLabel} If($i -in $YAxisTitleStartIdx..$YAxisTitleEndIdx){ $YAxisLabelAlphabet = $YAxisTitle[$YAxisTitleAlphabetCounter]+" " $YAxisTitleAlphabetCounter++ } else { $YAxisLabelAlphabet = ' ' } # To color the graph depending upon the datapoint value If ($i -gt 7) {Write-Host $YAxisLabelAlphabet -ForegroundColor DarkYellow -NoNewline ;Write-Host "$YAxisLabel|" -NoNewline; Write-Host $Row -ForegroundColor Red} elseif ($i -le 7 -and $i -gt 4) {Write-Host $YAxisLabelAlphabet -ForegroundColor DarkYellow -NoNewline ;Write-Host "$YAxisLabel|" -NoNewline; Write-Host $Row -ForegroundColor Yellow} elseif($i -le 4 -and $i -ge 1) {Write-Host $YAxisLabelAlphabet -ForegroundColor DarkYellow -NoNewline ;Write-Host "$YAxisLabel|" -NoNewline; Write-Host $Row -ForegroundColor Green} else {Write-Host "$YAxisLabel|"} } $XAxis # Prints X-Axis horizontal line Write-Host $XAxisLabel -ForegroundColor DarkYellow # Prints XAxisTitle } |
