# How do I chart cycle time, throughput and aging work?

Open **Layout** in a chart view's toolbar and set the fields below. **Cycle time** and **Cycle time end date** are a duration measure's fields, listed under **Status history**.

## Cycle time histogram

1. Set **Chart type** to **Bar** and the **Y-axis** to **Count (items)**.
2. Set the **X-axis** to **Cycle time**.

## Throughput per week

1. Set **Chart type** to **Bar** and the **Y-axis** to **Count (items)**.
2. Set the **X-axis** to **Cycle time end date**.
3. Set **Group dates by** to **Week**.

## Cycle time scatter

1. Set **Chart type** to **Scatter**.
2. Set the **X-axis** to **Cycle time end date** and the **Y-axis** to **Cycle time**.
3. To show only recent work, filter the view on **Cycle time end date**.

## Aging work in progress

1. Filter the view to items that are not finished.
2. Set **Chart type** to **Scatter**.
3. Set the **X-axis** to **Status** and the **Y-axis** to **Time in Status**.

> **A reopened item leaves the throughput count** until it is finished again, because its measure has no end until then. See [How duration measures work](../../how-it-works/duration-measures/).
