Excel Cube functions explained: Cubevalue, Cubeset, Cubemember

All these vectors get stored in an embedding which is like a room with many dimensions. Each value in a… Read More »Are vector-databases the new craze?

Power BI: add KPI arrow triangles to your Variance Metrics

Anybody up for coloring Egyptian pyramids with Power BI? Just kidding 🙂 How about creating nice looking triangle arrows for your comparison measures colored dynamically based on the values.
