Actually it is related to new fields/buttons that was added without taking into account the tab indicators functionality.

Affected places: Graph widget (Axes (release 7.2/master)/Legend tabs (release 7.0, 7.2, master)), Pie chart widget (Legend tab (release 7.0, 7.2, master))

Note: Please check if there are other places where this logic can be missed.

Steps to reproduce:

Case 1

• Open graph widget Axes tab
• Change Scale option from Linear (default value) to Logarithmic
• Check Axes tab

Case 2

• Open graph widget Legend tab
• Change Rows from Fixed (default selected radio button) to Variable
• Check Legend tab

Result: green dot indicator in tab is missing.

Expected: the green dot should be displayed when the configuration differs from the UI default.
