You can save a new analysis from the dashboard, make changes to it and then publish a new dashboard. When you publish, you won’t see the option to replace the original.
If you really need to replace the original dashboard instead of creating a new one, I think there may be a way with the API but I haven’t tried it myself.
- After you save the new analysis from the original dashboard, use it to create a template by specifying it as the source analysis in the request body.
- Then use the UpdateDashboard operation to update the original dashboard by using the template you created.
