I have a grid displaying stocks and production of resources (related to my previous question).
Should I display a plus symbol (+) in front of the production number when it's positive? Or do you think displaying the number is enough and the plus symbol is unnecessary?
The answer depends on whether its an incremental value or total value. For example, consider the StackExchange website. When you get reps, you see +10 as notification whereas there's no (+) in front of your total reputation because it's a total value. If the production of resources is changing with time, I would recommend using (+) provided you're showing the total value somewhere in the UI. In your UI, if the stock value = total value, you can use (+) to show increment in production.
