In the following hand made charts I show some value for years. In the first chart I've evenly spaced each year. On the second chart I've spaced them relativelly to their actual year value within time (i.e 2016 is closer to 2017 than 2010).
Is there a terminology for the spacing of the second chart? Imagine building a software which would have a toggle control to switch the view from A to B. How would you call it?
