A breakdown is a view of your main graph. It shows the distribution of values for the aggregated plots in your graph. For example, you can create a breakdown for a graph on the request field to see the distribution of request values for the HTTP response codes you plotted in Add a Plot to a Graph. You can add different types of breakdowns depending on the kind of information you want to see, in this case you'll create a histogram breakdown. ## Create a Histogram Breakdown 1. Open the graph created in [Create a Graph](/docs/create-a-graph) and [Add a Plot to a Graph](/docs/add-a-plot-to-a-graph). 2. Expand the downward arrow under the center of the graph. 3. Select a breakdown type of **Histogram**. 4. Set field name to **Response**. 5. Click the **Add Breakdown** button. The histogram shows a breakdown of the three plotted queries and which code returns the most HTTP responses. In this example, the response code 404 returns the most.

Each graph can have five breakdowns. ## Pie Chart Breakdown With a pie chart breakdown, you can see how the response codes are distributed across hosts. 1. Click **+Add.** 2. Select breakdown type **Pie.** 3. Distribute by **Fields.** 4. Set field to **Host**. Hover over each part of the pie chart to see the hosts. In this example we can see a host that has a large number of 404's compared to the other hosts. There are no 500 response codes returned.
