Make a line to the write from the last know data

I want to know if it is possible to automatically draw a line to the write from the last know data in a time series. So that there is always something to show also when the was no update of that data in the selected time. I am using grafank v9.1.6 installed on a raspberry pi.

Hope someone can help!
