How to create a progress bar

[AfterLife6]

HI!

IM playing enthusia (ps2 game), and i ve maked a list in escel, of the cars, beacause i want to collect them all.
Is there a way, to create a progress bar, for example, when i put an X, in front of a car, the bar raises, and it shows the %.

You could use a COUNTIF formula to count the # of Xs in the column, which you divide by the row count, then have a simple graph that shows the result on a 0-100 scale.
