Cumulative sum doesn't use field formatter to render values

[fbaligand]

If I render a chart with cumulative sum as metric (based on a sum of a "My Field" per date histogram), "My Field" format pattern (defined in kibana management) is not used to render the metric. Instead, default format pattern is applied.
=> It would be great to use field format pattern to render cumulative sum.

In this example, my field format pattern is "0,0.00", and I get this wrong render format :

This was probably fixed with #11933

Nice !
Any chance to backport this fix to 5.5.x branch ?
