When to use it
Section titled “When to use it”Bands stacked to a full 100% at every time bucket — the chart for how the mix shifted, independent of whether the total grew or shrank. “Mobile went from a third of traffic to two thirds” is exactly this chart.
Field wells
Section titled “Field wells”| Well | Accepts | Notes |
|---|---|---|
| X Axis | dimension | |
| Values (Y) | measures | multiple measures = multiple series |
| Series / Color | dimension | splits each value into one series per category value |
| Tooltip | fields | extra fields shown on hover |
Measure wells carry a quick-calc dropdown (running total, YoY %, % of total, …); SquareX measures drop in like any field.
- Because every column is normalized, a shrinking segment can still mean growing absolute numbers — say which you mean, or pair it with a total.
