I had to use the idea of this post as well. It highlights strict ordering of Start and End Dates of Easy Chart.

[Error with property binding on Easy Chart Start Date](http://forum.inductiveautomation.com/t/error-with-property-binding-on-easy-chart-start-date/18008)

I used a propertyChange script and I checked if my Newly Selected End Date was newer or older than Previously Selected End date. Then I applied either the End Dates 1st to Easy Chart or the Start Dates 1st to Easy Chart depending on if your moving forward in time with your selection or backwards.
