Hi,

I am trying to create a timelion chart with the aim of plotting the trend over time of my **size** field.  
I would like the line to continue in the future with the latest available data after today's date.

I am using version 8.1.3  
This is my timelion expression:  
`.es(index=my_index, q=field:value, metric=sum:size, timefield=timestamp).fit(nearest).label(size).divide(1024).precision(3)`

In version 5.4.0 my graph worked with this expression.

This is the current result:

Thanks

Daniele
