# Lot Quantity Bar Chart

The **Lot Quantity Bar Chart** widget shows how much material is currently in an asset or area. An area includes everything in its child assets. Its data comes from [getLotQty](../../../systemFunctions/lot/getLotQty.md).

1. Create a dashboard with the **Asset Selector**, **Date Range Selector** and **Lot Quantity Bar Chart** widgets, and save it.
2. Select `CoreForge\Philadelphia\Storage`. The chart includes Receiving, Bins and Shipping.
3. Group by **Item** to see the raw materials you received.
4. Group by **Asset**, then run a transfer and watch the quantity move.
5. Select `CoreForge\Philadelphia` and group by **State** to see OK and Scrap quantities. Group by **State Reason** once you've configured reasons in the [Lot States](../03-guiding-lot-operations/2-lot-states.md) elective.

The chart is a picture of current inventory. It can't tell you what went into a lot; use Lot Manager and the trace views for that.
