Help Needed Ecobee

I am using smartthings with an ecobee3 and graphing various data with Grafana.

The unit provides data via thermostatStatus. Example below from influxDB:

any thoughts on how i can add an interval graph for heating or cooling? i don’t care much about what it is heating or cooling too, i mostly want to be able to look at see that it has been running heat for the past X minutes before it goes idle.
