Line charts with PSU (coding question)

Product: PowerShell Universal
Version: 5.0.15

I have an unusual request.
Usually I tend to find out solutions on my own when scripting.
But the charts drive me crazy.
I have successfully created complex charts with powershell an windows.forms GUIs.
However I don’t seem to be able to get a nice line chart in PSU done.
Data is a table with a datetime column and several data columns.
The idea is to display the datetime on x, and the data values on y in a line chart.
The x labels should only appear every other month, even so the data is daily.

I don’t care if it is Nivo or JS.

Does anyone has an example that shows how to use all the options to customize the chart as needed.
I can only get the basics done.

Thanks.
