A query without a breakdown returns a single value, such as a total count of views. Add a *breakdown* to split that value into categories. For example, given a query of total views, you might add a breakdown for country so you can see where views come from.

## Add a breakdown{% #add-a-breakdown %}

Click Add breakdown to add up to four breakdowns to a single query. Each breakdown appears as a row under compared by in the query builder.

Each breakdown you add splits the results into ever smaller values. For example, a query broken down by both browser and country returns one bucket for each browser-and-country combination in your data, such as Chrome/United States and Chrome/Germany.

## Choose a measure{% #choose-a-measure %}

By default, a query measures the count of All events.

   alt="The default count of all events in the Analytics chart builder." /%}

Change All events to a different value to see a unique count of the specified value. For example, selecting Browser Name returns the number of distinct browsers that viewed a page.

   alt="A unique count by browser in the Analytics chart builder." /%}

Change the measure to a statistical aggregation of a numerical facet, such as loading time. Choose average, minimum, maximum, median, sum, or a percentile (75th, 90th, 95th, 98th, or 99th).
