How to Use

Create the collection: ClearCollect(colLineMulData, {month: "January", Category1: 186, Category2: 80}, {month: "February", Category1: 305, Category2: 200}, {month: "March", Category1: 237, Category2: 120}, {month: "April", Category1: 73, Category2: 190}, {month: "May", Category1: 209, Category2: 130}, {month: "June", Category1: 214, Category2: 140})
On your screen's OnVisible, add: Set(varAnimLineMulChart, true); Set(varTooltipLineMulIdx, 0)
Paste the copied YAML into Power Apps Studio (Ctrl+V).
Click any data point to show a tooltip with both Category 1 and Category 2 values; click again to dismiss.
To replay the animation: Set(varAnimLineMulChart, false); Set(varAnimLineMulChart, true)
Replace colLineMulData with any data source that has {month, Category1, Category2} columns.

Problem Solved

Renders a smooth dual-series SVG line chart inside a Power Apps Image control with a grow-up animation. No external charting library needed.

Integration

Bind colLineMulData to any data source with {month, Category1, Category2} columns. The chart redraws automatically when the collection changes.
