Bar Chart

A bar chart that can display output from scripts and APIs.

About

Bar 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 Y axis and Value as the X 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.

‚Äč
@(
@{
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.
