Fillgradient in scatter graphs

[wrowlands3]

Describe the solution you'd like
Scatter fillgradient defaults to fillcolor when used in home assistant, could support for this be added in a future release or am I missing something? It would be great to use colorscale in the fillgradient.

How would it be defined in yaml?

type: custom:plotly-graph
entities:
  - entity: ''
    y: 1
    x: $ex [new Date(Date.now()).setHours(-24), new Date(Date.now()).setHours(-23), new Date(Date.now()).setHours(24)]
    fill: tozeroy
    fillgradient:
      colorscale:
        - 0, red
        - 1, blue
      start: 0
      stop: 1
      type: vertical
hours_to_show: 24

I didn't know about fill gradients.
I suggest you try using this in plain plotlyjs, I don't think this card changes anything about it.
