Allow specifying horizontal range of barchart

[mvarble]

Currently, the bar chart only tracks the heights of the bins and not the "edges" of each bin. An unfortunate downside of this is that when I have a distribution of scalar data that I would like to view in a histogram, I have no idea where the mean is. Consider an animation like below, where the number of bins stays constant, but the mean moves.

I believe animations such as this could be achieved by extending the BarChart component to have edges and the BarChart blueprint to have view bounds.

Gah, I am sorry for spam. I must have searched histogram or some other related term that didn't cause a match.

no worries tickets are super hard to navigate and I'm keeping this open since it's actually a bit of a different aspect
