Use an attribute as the predicted value on Grafana time-series graph

In my influxdb, I have a measurement with two attributes, price and forecast_price.

-------------------------
|price | forecasted_price|
|12    | x               |
|13    | 14.1            |
--------------------------

On my Grafana time-series dashboard, I would like to use ONE SINGLE LINE to show the price attribute. Yet, beyond the end of the line, there will be a datapoint showing the value of the latest forecasted_price (i.e. 1-step ahead forecast), which is 14.1.

Is this possible given that influxdb and grafana are strict time-series tools?

Hello :wave: and welcome to the forum, @phuongdoan13

are you talking about metrics forecasting like this?
