Title: Custom valueFormatter when interactive guideline is used.

The interactive guideline feature previously forced display of the value in the tooltip to fit a fixed convention, which was inconsistent with the configuration available elsewhere for tooltips and the y axis. A configuration option was added to allow a custom valueFormatter to be passed, which we use to display the original data value rather than the percentage passed in the data.
