[kkoynov]

Is your feature request related to a problem? Please describe.

Currently I don't see a way to setup the Range slider so the thumbs could represent dates.

Describe the solution you'd like

I would like to be able to up the Range Slider similar to the slider on this page https://www.revealbi.io/reveal-sdk-samples/upmedia/home/Sales
