About

Line charts can retrieve output from scripts and APIs to display the data in a chart.‌

Display Data from an API

You will need to return an array of JSON objects from your API in order to use a bar chart. An example would be returning a list of hashtables serialized to JSON.

@(
    @{
        Name = "Name1"
        Value = Get-Random
    }
    @{
        Name = "Name2"
        Value = Get-Random
    }
    @{
        Name = "Name3"
        Value = Get-Random
    }
) | ConvertTo-Json

In this example, you would configure the data source to an API and select your API endpoint.

You would then specify Name as the X axis and Value as the Y axis.​​

The resulting chart contains the data from the API. Each time the page is loaded, the API is called.​

Display Data from a Script

You will need to return PSCustomObjects, objects or hashtables from your script in order to display a chart from a script.

​
@(
    @{
        Name = "Name1"
        Value = Get-Random
    }
    @{
        Name = "Name2"
        Value = Get-Random
    }
    @{
        Name = "Name3"
        Value = Get-Random
    }
) 

You will need to set the data source to script and select the script you want to retrieve data for.​

You will need to set the Y and X axis to the properties of the object returned from the script.​‌

The chart will appear on the page like this. Loading the page will not call the script again. It will load the result of the last time the script ran.​
