When you add a chart web part to a page, you’re left with the ‘Data & Appearance’ and ‘Advanced Properties’ toolbar links. Unfortunately, they can’t be hidden through the web part configuration user interface.
- Open the ASPX page in Designer.
- Use Code View and find the web part.
- Edit the ShowToolbar property from ‘True’ to ‘False’.
- Save changes.
The links are hidden – the web part drop down still shows them and allows access to use them without reseting the ShowToolbar property.
