Y-axis and height metrics
What the y-axis represents, choosing groupings, drilling, and resizing.
The Y-axis controls what is in each row of the river. The height metric controls how thick each band is drawn. Use both controls to define the rows and their scale.
What the y-axis represents
Each row is one value of the dimension you group by: one distributor, one product category, one SKU. Pick the dimensions from the Configure gear next to the Y-axis breadcrumb:


Select a dimension to add it. Drag its grip to change the order. Select more than one dimension to create a hierarchy. For example, Distributor → Distribution Center nests each company's accounts under that company. The available dimensions come from your organization’s configured data. Use the labels shown in your dialog; your organization may use different customer, product, or channel dimensions. Changes apply as you select or reorder dimensions. Clear all removes the selected groupings.
Up to two dimensions render as visible Y-axis columns. Additional dimensions collapse into a +N chip.
Drilling in and out
Click a cell in the Y-axis to drill into it. The river filters down to that value's contents. The breadcrumbs above the Y-axis show the active path:


Click a breadcrumb segment to step back. Click All to return to the top level. Drilling is also available from a band's right-click menu. Filters applied from elsewhere appear as removable chips in the same bar.
Choosing a height metric
Click the measure button in the toolbar, such as Revenue, to choose what band thickness represents.


The list shows measures available to your role, such as revenue, profit, quantity, support cases, and custom measures. The chosen metric drives segment thickness. The toolbar’s Display options also affect band size. Proportional bands gives higher-volume bands more row height. Log scale compresses differences between large and small values. Turn Log scale off for linear thickness scaling. Switching the metric reflows the entire river.
For measures configured as lower-is-better, such as support cases, the growth and decline colors flip so that an increase reads as bad.
Resizing
Drag the right edge of the Y-axis panel to widen or narrow it. Long labels that do not fit appear in a hover card.
