In web dashboard view in advanced settings for comparison timeframe can't we show on the same dashlet? Also when i tried comparison timeframe am getting single dashlet not like in your screenshot above. Please let me know if am missing something.
Please find the screen shot below. Am trying to chart sum of failures from Business Transaction. In left Y Axis i have selected the failures which has 30 splits and in Right Y Axis again i have selected same failures measure without splitting assuming as i need total sum as single line from yesterday's. But it's just matching with both the charts. Please correct me if am missing something here,
