Changing date range on easy chart

Hello, I have an easy chart that is set to historical mode and I have bound the start date with dateArithmetic(now(), -12, “hours”) and the end date with now() which works fine however my problem is now I cant change the date range as it just resets to the expression, how would I be able to change the date range but still have it show live values when i open the trend?

Try using now(0). That should turn off polling. :slight_smile:
