# Read the Brand / Model Sales Share chart

The Brand / Model Sales Share chart shows how sales split across brands and model codes, as a two-ring donut chart. The header reads **{n} sales · {revenue}** for the current brand selection.

### How to read the rings

* The **inner ring** shows each brand's share of sales.
* The **outer ring** shows each model code's share of sales, grouped under its brand.
* Both rings are sorted by sales volume, largest slice first.

Hover over any slice to see its details: the brand (or brand and model code together), **Sales volume: {n} ({percent}%)**, and **Revenue: {amount} ({percent}%)**. A text list titled "Sales chart values" below the chart lists the same brand figures for screen readers.

### Where you see it

This chart sits in the "Brand / Model Sales Share" card on the Aftermarket Analytics tab, next to the Model Performance table. Below the chart, a separate line covers unknown model/brand sales, the portion of sales Signal could not match to a specific model.

### Notes

* On a phone or narrow screen, both rings shrink so they still fit side by side.
* While data is loading, the card shows "Loading chart data…". When there is nothing to chart, it shows "No brand/model sales available for the current selection."
* This feature may not be enabled for your organization. Ask your Zephyr Intel contact.
* If your organization's sales data has not been connected, this chart shows its empty-state message instead of a chart.
