Display data before time range

Hello
I have a problem with influxRaw and last value before my range ($timeFilter)
I explain:

T0 to T100s, i have T10 = 1, T20 = 2, T50 = 1. …

If i display time between T0 and T100 i see all my values,
If i display time between T9 and T100 i see all my values too
If i display time between T11 and T100, i have a blank part at T11 up to T20

So, it means at T20 i can not know the previous value easily.

In picture1, you can see all data
In picture2, if the point is out of range, i have half graf in blank.

So my question, how can i fix it ? i’m just trying to display the historical value before.


Thank you for all your help :slight_smile:
