Deneb Line Chart using "repeat"

[Anonymous]

Hi everyone,
I am trying to make a multiple views line chart in @deneb. Its a replication of what Power BI guy made in this video.(link attached at the end). My line chart however, has two scenarios: Act and Bud. I was able to get those. However, I want budget line to be a dotted line and I am not able to get it. Could you please help with it?
Power BI file and Code attached below:
What I can do so far:

Hi @Anonymous ,

Maybe you can use the layer operator.

Sometimes, it’s useful to superimpose one chart on top of another. You can accomplish this by using the layer operator. This operator is one of Vega-Lite’s view composition operators. To define a layered chart, put multiple specifications into an array under the layer property.

For more details, refer to:

Layering views | Vega-Lite
