KPI : Backgroud trend disappear

Hi Team,

I have created KPI and provided all required field. Here I am able to the expected value in KPI and background trend but when I checked after applying filter the background trend gets disappear. When i troubleshot I found that the data for applied filter is missing for 1 or 2 months out of 6 month. Thats the reason the trend gets disappear.

Any one here have any workaround to this.

Thanks and Regards,

Swapnil
