Picked this up on the internet Smile Great extension to Powershell and .NET

What you need to get started is the

Microsoft Chart Controls for Microsoft .NET Framework 3.5

The Charting Controls documentation is here :

Microsoft Chart Controls for .NET Framework Documentation


Once installed you are ready to go, here is an example script showing the top 5 largest files in a directory.


If you hit the “Save button” it will save the graph to the desktop.

Here is the script :


if([Reflection.Assembly]::LoadWithPartialName("System.Windows.Forms.DataVisualization") -eq $null)
    #Microsoft Chart Controls are not installed
    [void][reflection.assembly]::Load("System.Windows.Forms, Version=,`
    Culture=neutral, PublicKeyToken=b77a5c561934e089")
    [void][System.Windows.Forms.MessageBox]::Show("Microsoft Chart Controls for Microsoft .NET 3.5`
    Framework is required", "Microsoft Chart Controls Required")
    #Open the URL
    return $false

# load the appropriate assemblies 

# create chart object 
$Chart = New-object System.Windows.Forms.DataVisualization.Charting.Chart 
$Chart.Width = 500 
$Chart.Height = 450
$Chart.Left = 40 
$Chart.Top = 30
# create a chartarea to draw on and add to chart 
$ChartArea = New-Object System.Windows.Forms.DataVisualization.Charting.ChartArea 

# add data to chart 
$Files = dir $env:USERPROFILE -Recurse -File | sort length  | select -last 5 # | % {"$_.Name " + [math]::Round(($_.Length / 1MB),2)}
$FileNames = @(foreach($File in $Files){$File.Name}) 
$FileSize = @(foreach($File in $Files){[math]::Round(($File.Length / 1MB),2)}) 

$Chart.Series["Data"].Points.DataBindXY($FileNames, $FileSize)

# add title and axes labels 
[void]$Chart.Titles.Add("Top 5 Files - Descending") 
$ChartArea.AxisX.Title = "File Name" 
$ChartArea.AxisY.Title = "File Size - [MB]"

# Find point with max/min values and change their colour 
$maxValuePoint = $Chart.Series["Data"].Points.FindMaxByValue() 
$maxValuePoint.Color = [System.Drawing.Color]::Red 

$minValuePoint = $Chart.Series["Data"].Points.FindMinByValue() 
$minValuePoint.Color = [System.Drawing.Color]::Green

# change chart area colour 
$Chart.BackColor = [System.Drawing.Color]::Transparent

# make bars into 3d cylinders 
$Chart.Series["Data"]["DrawingStyle"] = "Cylinder"

# display the chart on a form 
$Chart.Anchor = [System.Windows.Forms.AnchorStyles]::Bottom -bor [System.Windows.Forms.AnchorStyles]::Right -bor 
                [System.Windows.Forms.AnchorStyles]::Top -bor [System.Windows.Forms.AnchorStyles]::Left

# sorting the dataset
$Chart.Series["Data"].Sort([System.Windows.Forms.DataVisualization.Charting.PointSortOrder]::Descending, "Y")

# add a save button 
$SaveButton = New-Object Windows.Forms.Button 
$SaveButton.Text = "Save" 
$SaveButton.Top = 500 
$SaveButton.Left = 450 
$SaveButton.Anchor = [System.Windows.Forms.AnchorStyles]::Bottom -bor [System.Windows.Forms.AnchorStyles]::Right 
$SaveButton.add_click({$Chart.SaveImage($Env:USERPROFILE + "\Desktop\Chart.png", "PNG")}) 

# save chart to file 
$Chart.SaveImage($Env:USERPROFILE + "\Desktop\Chart.png", "PNG")

$Form = New-Object Windows.Forms.Form 
$Form.Text = "PowerShell Chart" 
$Form.Width = 600 
$Form.Height = 600
