Based on the research I've done within the past half hour, you need to download the Microsoft Chart Controls (https://www.microsoft.com/en-us/download/details.aspx?id=14422). This script (https://gallery.technet.microsoft.com/scriptcenter/Charting-Line-Chart-using-df47af9c)
creates a line chart, using the Chart Controls.
To input data from your CSV files, modify the lines in the script:
#physical memory
[void]$MemoryUsageChart1.Series.Add("PM")
$MemoryUsageChart1.Series["PM"].BorderWidth = 3
$MemoryUsageChart1.Series["PM"].ChartType = [System.Windows.Forms.DataVisualization.Charting.SeriesChartType]::Line
$Processes = Get-Process | Sort-Object -Property WS | Select-Object Name,PM,VM -Last 5
$ProcessList = @(foreach($Proc in $Processes){$Proc.Name + "`n"+[math]::floor($Proc.PM/1MB)})
$Placeholder = @(foreach($Proc in $Processes){$Proc.PM/1MB})
$MemoryUsageChart1.Series["PM"].Points.DataBindXY($ProcessList, $Placeholder)
#virtual memory
[void]$MemoryUsageChart1.Series.Add("VM")
$MemoryUsageChart1.Series["VM"].BorderWidth = 3
$MemoryUsageChart1.Series["VM"].ChartType = [System.Windows.Forms.DataVisualization.Charting.SeriesChartType]::Line
$Processes = Get-Process | Sort-Object -Property WS | Select-Object Name,PM,VM -Last 5
$ProcessList = @(foreach($Proc in $Processes){$Proc.Name + "`n"+[math]::floor($Proc.VM/1MB)})
$Placeholder = @(foreach($Proc in $Processes){$Proc.VM/1MB})
$MemoryUsageChart1.Series["VM"].Points.DataBindXY($ProcessList, $Placeholder)
And to put the column data from your csv files into an array, you could probably run a command like:
Import-CSV "example.csv" | ForEach-Object {Write-Host 'ColumnName=' +$_.ColumnName}
