# Save a custom chart as a workspace chart and reuse it

> Save a Mammoth custom chart as a workspace chart, add it to any dashboard from the Custom chip, delete it, and see who can save and how many you can keep.
>
> Applies to: Roles: Workspace owners, admins and members save or delete; anyone who can edit the dashboard adds one. Where: Dashboard editor › Add › Chart › Custom

A workspace chart is a [custom chart](https://mammoth.io/docs/learn/dashboards/custom-charts/) saved so anyone in your workspace can add it from the **Custom** chip, on any dashboard. Workspace owners, admins and members can save and delete them; anyone who can edit a dashboard can add one.

You can only save a custom chart that's already on a dashboard, not from the **Add a chart** dialog.

## Save a custom chart

1. Click the custom chart on the canvas to open it in the edit panel.
2. In **Save as a workspace chart**, type a **Name**.
3. Check the **Needs:** line. It lists the columns a dashboard must have to use this chart, such as "a Region column".
4. Click **Save as a workspace chart**. "Everyone in this workspace can add it from the Custom chip."

On success, you see "Saved to your workspace charts." The button reads **Saved** until you change the name or the recipe, so you can't save a duplicate by clicking twice.

## Add a saved workspace chart to a dashboard

1. Click **Add** → **Chart**, then the **Custom** chip.
2. Look under **Your workspace charts**, with a count such as "3 saved". Each tile shows the chart's name, a thumbnail and who saved it ("saved by" and their name).
3. Click one. The studio opens with the chart drawn on this dashboard's data.
4. Click **Add chart**.

A tile is disabled, with a note such as "Needs a Region column", when this dashboard's data doesn't have a column the chart needs.

The dashboard gets its own copy of the chart. Later changes to the saved chart, or deleting it, don't affect dashboards that already use it. The new chart is titled from its data, not from the saved name. Workspace charts aren't offered on comparison pages.

## Delete a workspace chart

1. Click **Add** → **Chart** → **Custom**.
2. On the chart's tile, click **⋯** → **Delete**.
3. Confirm the question that names the chart, for example "Delete Pipeline?" ("Boards that already use it keep their copy."). Click **Delete**.

If it fails, you see "Couldn't delete it. Try again."

## Who can save and delete workspace charts

Any owner, admin or member can delete any workspace chart, not only the ones they saved. Guests, and dashboard editors with no workspace role, don't see the save section or the **⋯** menu. See [Members, roles and custom roles](https://mammoth.io/docs/learn/workspace/members-and-roles/).

## Limits for workspace charts

| Limit | Rule |
|---|---|
| Workspace charts per workspace | Up to 200. Delete one to save another. |
