Graph filter by custom field

Using Ralph
1

Hi,

I’ve been looking into Ralph for some time, We need to utilize custom fields to use in graphs filtering.

Are we able to filter custom fields ?

Please refer to my current code in graphs and i wanted to add custom fields inside the filter.

{
    "filters": {
        "location": "Unix",
        "model__category__name": "Laptop"
    },
    "labels": "location",
    "series": "location"
}

Thanks In advance for Help!
