You can extract the "Caption" of your indicator.
If you right-click your indicator in the Panel side, you will see the option "Show -> Caption". Select it so the caption is showed and write on it the name of the indicator.
On the Diagram side create an Attribute Node of your indicator. Right-click on the indicator symbol and select "Create -> Attribute Node". In the attribute node, right-click the attribute and select "Select Item -> Caption". Make sure the attribute node is on Read mode (you will see a small arrow at the right side of the attribute). Right-click the attribute node and select "Change to Read" if it is in write mode.
