I don't really follow the connection between the values you have, and then them being fixed.
With that said, you can probably use index()*(some number) to get what you want.
I built the viz they way I want it to appear and now I am trying to figure out a way for it to work with my data. So disregard the fixed values in my sample data I am now trying to replace it so that when using real data the chart will automatically place my groups in a equally separated way. I am not familiar with how to get what I want since the number of groups will change. There will always be 1400 Y values but there could be 7, 2, 9, or even 20 groups on either side so I was thinking to automatically divide 1400 by the count of groups and then assign each value to a group for the Y value.
