TThe purpose of this chart
Throughput is the rate of which work is finished in a given time period (items per day, week, etc.).
The throughput histogram is a bar chart that shows the distribution of your throughput. In other words it shows you how often you achieve a certain daily throughput.
How to read the chart
The vertical axis represents a Frequency. In this case, the frequency means the number of days you achieved a certain throughput.
The horizontal axis represents a Throughput. In this case, the number of items you completed in a day.
Hover over any bar to see the frequency of a given throughput.
In the chart to the right it clearly shows that, in most days, we deliver ZERO items.
But there were 75 days that we delivered one finished item, 40 days that we delivered two, 25 days that we delivered three and so on. As the throughput is less frequent, our expectation of it happening again should also reduce. These outcomes are less likely than the ones that happen often.

Cursor
You can select these items to get information on the data based on where you place your cursor. It can tell you the specifics of either, or both, of the throughput and the frequency.
Percentiles
When you choose this option, the chart looks at all of the work items represented by and draws percentile lines at spots.
These lines can be interpreted as "XX% of the time, our we finish X days or less per day"
In the image to the right, you can say that 70% of the time we finish 1 item or less per day, for example. Or, you could say that 95% of the time we finish 3 items or less per day.
Pro Tip
The higher you go up in percentage, the more outliers that it includes. You are, with this data, less likely to finish 3 items per day than 1. Remember, it is a 95% chance that you'll 3 items OR LESS per day, not 3 items or more.
Item Filter
You can filter down the items represented on this chart by choosing one or more available filters.
If you want to clear your filters so that all items are represented again, you click the Reset button.

When you choose -----------, the value on the relevant axis will be highlighted based on your cursor placement
Overlay
Choose whether or not you would like to add a cumulative percentile line. With this line, you can see how what percentage of your finished items are accounted for at any given point on the horizontal axis.
Workflow Stages
If you want to track the throughput of a smaller portion of your workflow, deselect the workflow stages you'd like to exclude.
