Codex Heatmap Matrix

Patterns hide in tables. Heatmaps reveal them instantly. Codex Heatmap Matrix renders a two-dimensional grid where cell colour encodes the value — making hotspots, clusters, and outliers immediately visible. It's the fastest way to identify patterns across a row-by-column matrix that would take minutes to read as a standard table. IDEAL FOR • Activity patterns — tickets, orders, or events by day of week and hour • Performance matrices — score by team and month, or accuracy by product and region • Resource utilisation — occupancy or load by resource and time period • Any two-dimensional cross-tab where relative magnitude matters KEY FEATURES • Full colour gradient across all cells from minimum to maximum value • Built-in colour schemes: green-to-red, red-to-green, or fully custom • Custom low, mid, and high colours for brand-aligned palettes • Null/zero cell colour configurable separately • Cell value labels with configurable number format • Corner rounding for a polished, card-like cell appearance • Sort order field well for column axis — control day/period ordering • Hover tooltip showing row, column, and cell value • Click a cell to cross-filter other visuals on the page PRO TIP Use the Sort order field well on the Column Category to enforce a logical order (e.g. Mon=1 through Sun=7). Without it, Power BI will sort day names alphabetically — Fri, Mon, Sat — which makes weekly patterns impossible to read.
