Type /year-range-slicer, point it at your chart(s), pick which periods to include, and the skill handles everything:

1. Reads your chart — finds the Y-axis measures, the calendar table, the year column, and whether a year slicer is anchoring the chart

2. Asks one thing — which periods you want on the buttons (CY, 2Y, 3Y, 4Y, 5Y), then shows you the plan and waits for your go

3. Builds the buttons — a small disconnected parameter table, one row per period, that drives the slicer

4. Wraps your measures — for each measure on the chart it creates a version that shows the value inside the chosen window and returns blank outside it, so out-of-window bars just disappear (no visual-level filter involved)

5. Handles the axis automatically — when a year slicer anchors the chart it swaps the axis to a disconnected table and bridges back to the data (via TREATAS) so prior years still show; when no year slicer is involved it leaves your live axis alone and only swaps the measures

6. Adds a self-updating title — names the selected window and anchor year, e.g. "Revenue – 2Y (2013–2014)"

7. Drops in the slicer — a compact tile slicer top-right above the chart, styled to match your page, pre-set to CY

8. Keeps interactions clean — the slicer drives only its own chart and stays out of everything else (and other visuals can never override it)

9. Follows bookmarks — if the chart shows and hides with a bookmark, the slicer is grouped with it so they travel together
