I have a graph with an Y-axis of 8 numbers:
0, 20, 40, 60, 80, 100, 120, 140%
The 8 numbers spread equally across a vertical line that is 100%. That means each number equals to 12,5% on the vertical line.
Lets assume I need to define a bar on this graph that equals to 52% or 125%. How would I go about calculating how much that would equal to (percentage'wise) on the vertical line?
