getting power BI tooltips on Deneb line chart

[jonespossibly]

I'm using the wonderful Deneb custom visual, but don't seem to be able to get power bi tooltips on a line chart - hopefully with drill through.  it works fine on a bar chart, but lines seem to not care how much i hover and where.

any hints?

ok, so i think that my issue is with me using an aggregate in my mark encoding.  looks like the tooltip won't appear if you do this:
"y": {
"field": "Weekly Avg Enquiries",
"aggregate": "sum"
},

Hi @jonespossibly ,

Please add "tooltip": true to your code:

{
  "data": {"name": "dataset"},
  "layer": [
    {
      "mark": {"type": "line","tooltip": true},
      "encoding": {
        "y": {
          "field": "Weekly Avg"
        },
        "color": {
          "field": "Loan Type",
          "scale": {
            "range": [
              "#4795CA",
              "#F9B96A",
              "#779E41",
              "#F54f0F",
              "#cfcfcf"
            ]
          }
        }
      }
    },
    {
      "mark": {"type": "line","tooltip": true},
      "encoding": {
        "y": {
          "field": "Weekly Avg",
          "aggregate": "sum"
        },
        
        "color": {"datum": "Total"}
      }
    },
    {
      "mark": {
        "type": "line",
        "strokeDash": [5, 5]
      },
      "transform": [
        {
          "regression": "Weekly Avg",
          "on": "WC",
          "groupBy": "WC"
        
        }
      ],
      "encoding": {
        "y": {
          "field": "Weekly Avg"
        },
        "color": {"datum": "Trend"}
      }
    }
  ],
  "encoding": {
    "x": {
      "field": "WC",
      "timeUnit": "monthdateyear",
      "type": "ordinal",
      "axis": {"format": "%d/%m/%Y"}
    },
    "y": {
      "type": "quantitative",
      "axis": {"format": "~s"}
    }
  }
}

It is finicky. You need to put the very tip of the mouse on where the points would be (and make sure you the "tooltip": true .
