Create a calculation field: TC_THERMOMETER VALUE, type function:
Drag and drop the calculation field "TC_THERMOSETER VALUE", then right-click the capsule, and calculate the calculation based on the drop-down menu: PATH (data barrel).
4. Create a calculation field: tc_size (container), type function:
IF [Index] = 0 THEN 1 ELSE 0 END
Create a calculation field: tc_size (Thermometer), type function:
IF [Index] = 0 THEN 1 ELSE 0 END
In the "Index" tag, click Color, set the color to: gray.
