What's the intended use of the serial number field on assets? It has a uniqueness constraint enforced, but across different hardware model lines serial numbers may not actually be unique.

Can somebody please help with the graph syntax?
Target is to have graph to see how many servers were bought on each year.
Axis X - years, Axis Y - amount. Date is stored in invoice_date field.
I've made a graph with following settings:

Model: data center asset

Aggregate type: Count

Chart type: Vertical Bar


    "filters": {},
    "labels": "invoice_date",
    "series": "invoice_date"

It is doing what I want, but dates in Axis X are full dates with YYYY-MM-DD and randomly mixed 2012-08-12, 2017-05-22, 2009-06-13, 2012-09-10 etc...

Question is: How to aggregate dates to Year only and sort them, so I have in Axis X:
2009 - x servers
2010 - y servers
2011 - z servers

Ralph docs ( say I can use smth like this: "series": "invoice_date|year", but this gives an error "Series supports Only distinct (you put 'year')"

Django docs are not helping, as I am not familiar with it :(

Thank you!

@supaflyster try this:
    "filters": {
        "invoice_date__isnull": false
    "labels": "invoice_date|year",
    "series": "invoice_date",
    "sort": "year"
