$ResourceID = '/subscriptions/<subscription>/resourceGroups/demo-resource-group/providers/Microsoft.Compute/virtualMachines/SimpleWinVM'
$Data = Get-AzMetric -ResourceId $ResourceID  -WarningAction SilentlyContinue | Select-Object unit, data
$Datpoints = $data.data.average.foreach({[int]$_})

Import-Module Graphical
Show-Graph -Datapoints $Datpoints -GraphTitle 'CPU (% age)'

```
