# Edit a diagram on a Jira issue

To edit a diagram on a Jira issue, open the issue, select the diagram's tab in the **Diagram** panel and select **Edit**. Make your changes in the editor and select **Save**. Saving replaces the diagram's attachment, so the issue keeps one current copy rather than a history of versions.

---

## Before you start

* You can add and delete attachments on the issue.
* If you might want the old version back, download the attachment first. There is no version history for Jira diagrams.

---

## Steps

1. Open the issue.
2. In the **Diagram** panel, select the tab of the diagram you want to change.
3. Select **Edit**.
4. Make your changes in the editor.
5. Select **Save**.

Editing a diagram from the Diagram panel. Change the source on the left, check the preview on the right, then select Save.

## What happens next

* The panel shows the new version straight away.
* The attachment is replaced: it now shows you as the author and today as the date, and the issue history shows a delete and an add.
* Anyone viewing the issue sees the change after their view refreshes.

## If it does not work

* **Edit** is missing, or does nothing: you cannot change attachments on this issue. See [Add, Edit or Delete buttons are visible but clicking them does nothing](https://help.gocapable.com/jira-diagrams/add-edit-or-delete-buttons-are-visible-but-clicking-them-does-nothing.html).
* The diagram disappeared after saving: see [Save appeared to succeed but the diagram is now missing from the issue entirely](https://help.gocapable.com/jira-diagrams/save-appeared-to-succeed-but-the-diagram-is-now-missing-from-the-issue-entirely.html).
