Charts

Charting components for Universal Dashboard.

Universal Dashboard provides several built-in charting solutions to help visualize your data retrieved from PowerShell.

ChartJS

Universal Dashboard integrates with ChartJS.

Creating a Chart

To create a chart, use New-UDChartJS and New-UDChartJSData. The below chart shows the top ten CPU using processes.

 $Data = Get-Process | Sort-Object -Property CPU -Descending | Select-Object -First 10 
 New-UDChartJS -Type 'bar' -Data $Data -DataProperty CPU -LabelProperty ProcessName

Types

Bar

 $Data = Get-Process | Sort-Object -Property CPU -Descending | Select-Object -First 10 
 New-UDChartJS -Type 'bar' -Data $Data -DataProperty CPU -LabelProperty ProcessName

Stacked Bar

    $GraphPrep = @(
        @{ RAM = "Server1"; AvailableRam = 128; UsedRAM = 10 }
        @{ RAM = "Server2"; AvailableRam = 64; UsedRAM = 63 }
        @{ RAM = "Server3"; AvailableRam = 48; UsedRAM = 40 }
        @{ RAM = "Server4"; AvailableRam = 64;; UsedRAM = 26 }
        @{ RAM = "Server5"; AvailableRam = 128; UsedRAM = 120 }
    )

    $AvailableRamDataSet = New-UDChartJSDataset -DataProperty AvailableRAM -Label 'Available' -BackgroundColor blue
    $UsedRamDataset = New-UDChartJSDataset -DataProperty UsedRAM -Label 'Used' -BackgroundColor red
    $Options = @{
        Type          = 'bar'
        Data          = $GraphPrep
        Dataset       = @($AvailableRamDataSet, $UsedRamDataset)
        LabelProperty = "RAM"
        Options = @{
            scales = @{
                xAxes = 
                @{
                    stacked = $true
                }            
            yAxes = 
                @{
                    stacked = $true
                }            
            }
        }
    } 

    New-UDChartJS @Options

Horizontal Bar

    $Data = Get-Process | Sort-Object -Property CPU -Descending | Select-Object -First 10 
    New-UDChartJS -Type 'bar' -Data $Data -DataProperty CPU -LabelProperty ProcessName -Options @{
        indexAxis = "y"
        plugins = @{
            legend = @{
                position = "right"
            }
        }
    }p

Bubble

A bubble chart consists of x and y coordinates and an r value for the radius of the circles.

$Data = @(
    @{ x = 1; y = 10; r = 15 }
    @{ x = 12; y = 25; r = 35 }
    @{ x = 8; y = 10; r = 95 }
    @{ x = 6; y = 95; r = 25 }
)
New-UDChartJS -Type 'bubble' -Data $Data 

Line

 $Data = Get-Process | Sort-Object -Property CPU -Descending | Select-Object -First 10 
 New-UDChartJS -Type 'line' -Data $Data -DataProperty CPU -LabelProperty ProcessName

Doughnut

 $Data = Get-Process | Sort-Object -Property CPU -Descending | Select-Object -First 10 
 New-UDChartJS -Type 'doughnut' -Data $Data -DataProperty CPU -LabelProperty ProcessName

Pie

 $Data = Get-Process | Sort-Object -Property CPU -Descending | Select-Object -First 10 
 New-UDChartJS -Type 'pie' -Data $Data -DataProperty CPU -LabelProperty ProcessName

Radar

 $Data = Get-Process | Sort-Object -Property CPU -Descending | Select-Object -First 10 
 New-UDChartJS -Type 'radar' -Data $Data -DataProperty CPU -LabelProperty ProcessName

Colors

Colors can be defined using the various color parameters of New-UDChartJS.

 $Data = Get-Process | Sort-Object -Property CPU -Descending | Select-Object -First 10 

 $Options = @{
   Type = 'bar'
   Data = $Data
   BackgroundColor = 'Red'
   BorderColor = '#c61d4a'
   HoverBackgroundColor = 'Blue'
   HoverBorderColor = '#451dc6'
   DataProperty = 'CPU'
   LabelProperty = 'ProcessName'
 }

 New-UDChartJS @Options

Data Sets

By default, you do not need to define data sets manually. A single data set is created automatically when you use the -DataProperty and -LabelProperty parameters. If you want to define multiple data sets for a single chart, you can use the -Dataset property in conjunction with New-UDChartJSDataset.

$Data = Get-Process | Sort-Object -Property CPU -Descending | Select-Object -First 10 

 $CPUDataset = New-UDChartJSDataset -DataProperty CPU -Label CPU -BackgroundColor '#126f8c'
 $MemoryDataset = New-UDChartJSDataset -DataProperty HandleCount -Label 'Handle Count' -BackgroundColor '#8da322'

 $Options = @{
   Type = 'bar'
   Data = $Data
   Dataset = @($CPUDataset, $MemoryDataset)
   LabelProperty = "ProcessName"
 }

 New-UDChartJS @Options

Click Events

You can take action when a user clicks the chart. This example shows a toast with the contents of the $Body variable. The $Body variable contains a JSON string with information about the elements that were clicked.

 $Data = Get-Process | Sort-Object -Property CPU -Descending | Select-Object -First 10 

  $Options = @{
   Type = 'bar'
   Data = $Data
   DataProperty = 'CPU'
   LabelProperty = "ProcessName"
   OnClick = { 
      Show-UDToast -Message $Body
   }
 }


 New-UDChartJS @Options

Auto refreshing charts

You can use New-UDDynamic to create charts that refresh on an interval.

New-UDDynamic -Content {
    $Data = 1..10 | % { 
        [PSCustomObject]@{ Name = $_; value = get-random }
    }
    New-UDChartJS -Type 'bar' -Data $Data -DataProperty Value -Id 'test' -LabelProperty Name -BackgroundColor Blue
} -AutoRefresh -AutoRefreshInterval 1

Monitors

Monitors are a special kind of chart that tracks data over time. Monitors are good for displaying data such as server performance stats that change frequently. You return a single value from a monitor and it is graphed automatically over time.

New-UDChartJSMonitor -LoadData {
    Get-Random -Max 100 | Out-UDChartJSMonitorData
} -Labels "Random" -ChartBackgroundColor "#297741" -RefreshInterval 1

Options

The New-UDChartJS cmdlet supports accepting advanced ChartJS options. You can use the -Options parameter to pass in a hashtable.

This example hides the legend.

 $Data = Get-Process | Sort-Object -Property CPU -Descending | Select-Object -First 10 
 New-UDChartJS -Type 'bar' -Data $Data -DataProperty CPU -LabelProperty ProcessName -Options @{  
 legend = @{  
     display = $false  
 }  
}

Title

You can include a title with the title option.

$Data = Get-Process | Sort-Object -Property CPU -Descending | Select-Object -First 10 
New-UDChartJS -Type 'bar' -Data $Data -DataProperty CPU -LabelProperty ProcessName -Options @{
    plugins = @{
        legend = @{
            title = @{
                display = $true
                text    = 'Bar Chart'
            }
        }
    }
}

Nivo Charts

Universal Dashboard integrates with Nivo Charts. Below you will find examples and documentation for using these charts.

Creating a Chart

All the Nivo charts can be created with New-UDNivoChart. You will specify a switch parameter for the different types of charts. Each chart type will take a well defined data format via the -Data parameter.

$Data = 1..10 | ForEach-Object { 
    $item = Get-Random -Max 1000 
    [PSCustomObject]@{
        Name = "Test$item"
        Value = $item
    }
}
New-UDNivoChart -Id 'autoRefreshingNivoBar' -Bar -Keys "value" -IndexBy 'name' -Data $Data -Height 500 -Width 1000

Patterns

Nivo provides the ability to specify patterns to display over data sets. You can configure these patterns with New-UDNivoPattern and New-UDNivoFill .

$Data = @(
    @{
        country = 'USA'
        burgers = (Get-Random -Minimum 10 -Maximum 100)
        fries = (Get-Random -Minimum 10 -Maximum 100)
        sandwich = (Get-Random -Minimum 10 -Maximum 100)
    }
    @{
        country = 'Germany'
        burgers = (Get-Random -Minimum 10 -Maximum 100)
        fries = (Get-Random -Minimum 10 -Maximum 100)
        sandwich = (Get-Random -Minimum 10 -Maximum 100)
    }
    @{
        country = 'Japan'
        burgers = (Get-Random -Minimum 10 -Maximum 100)
        fries = (Get-Random -Minimum 10 -Maximum 100)
        sandwich = (Get-Random -Minimum 10 -Maximum 100)
    }
)

$Pattern = New-UDNivoPattern -Dots -Id 'dots' -Background "inherit" -Color "#38bcb2" -Size 4 -Padding 1 -Stagger
$Fill = New-UDNivoFill -ElementId "fries" -PatternId 'dots'

New-UDNivoChart -Definitions $Pattern -Fill $Fill -Bar -Data $Data -Height 400 -Width 900 -Keys @('burgers', 'fries', 'sandwich')  -IndexBy 'country'

Responsive Widths

Nivo charts provide responsive widths so they will resize automatically when placed on a page or the browser is resized. A height is required when using responsive widths.

Auto Refreshing Charts

Like many components in Universal Dashboard v3, Nivo charts do not define auto-refresh properties themselves. Instead, you can take advantage of New-UDDynamic to refresh the chart on an interval.

New-UDDynamic -Content {
    $Data = 1..10 | ForEach-Object { 
        $item = Get-Random -Max 1000 
        [PSCustomObject]@{
            Name = "Test$item"
            Value = $item
        }
    }
    New-UDNivoChart -Id 'autoRefreshingNivoBar' -Bar -Keys "Value" -IndexBy 'name' -Data $Data -Height 500 -Width 1000
} -AutoRefresh

OnClick

Nivo charts support OnClick event handlers. You will be provided with information about the data set that was clicked as JSON.

$Data = @(
    @{
        country = 'USA'
        burgers = (Get-Random -Minimum 10 -Maximum 100)
        fries = (Get-Random -Minimum 10 -Maximum 100)
        sandwich = (Get-Random -Minimum 10 -Maximum 100)
    }
    @{
        country = 'Germany'
        burgers = (Get-Random -Minimum 10 -Maximum 100)
        fries = (Get-Random -Minimum 10 -Maximum 100)
        sandwich = (Get-Random -Minimum 10 -Maximum 100)
    }
    @{
        country = 'Japan'
        burgers = (Get-Random -Minimum 10 -Maximum 100)
        fries = (Get-Random -Minimum 10 -Maximum 100)
        sandwich = (Get-Random -Minimum 10 -Maximum 100)
    }
)
New-UDNivoChart -Bar -Data $Data -Height 400 -Width 900 -Keys @('burgers', 'fries', 'sandwich')  -IndexBy 'country' -OnClick {
    Show-UDToast -Message $EventData -Position topLeft
}
