In the image below, the green dashes represent having a percentage of something while the gray dashes represent not having that percentage. I might say, there are three active segments and three inactive segments. This is for technical documentation so conciseness is desired. There was a related question I saw about a word that describes the intervening spaces, and interstice was suggested, so hoping there is a word for this.
The credits progress bar should be divided into ______ for which some are green and some gray indicating amounts earned or not earned respectively.
Of course the word segment springs to mind, but thought there might be something else.
