How to Use

Create the collection: ClearCollect(colLineLblData, {month: "January", Value: 186}, {month: "February", Value: 305}, {month: "March", Value: 237}, {month: "April", Value: 73}, {month: "May", Value: 209}, {month: "June", Value: 214})
On your screen's OnVisible, add: Set(varAnimLineLblChart, true); Set(varTooltipLineLblIdx, 0)
Paste the copied YAML into Power Apps Studio (Ctrl+V).
Each dot shows its value as a label above it. Click any dot to show a tooltip; click again to dismiss.
To replay the animation: Set(varAnimLineLblChart, false); Set(varAnimLineLblChart, true)
Replace colLineLblData with any data source that has {month, Value} columns.

Problem Solved

Renders a smooth SVG line chart with dots and floating value labels above each point inside a Power Apps Image control, with a grow-up animation.

Integration

Bind colLineLblData to any data source with {month, Value} columns. The chart redraws automatically when the collection changes.
