Graphics on File Sensor

Configuration
1

Hi guys,
I’m importing some values from a file with JSON format. I already can see the values on HA but i would like to see those values showed as numeric and get a graph.

As you can se in the picture in this moment get the value as characters and dont show a graphic as other sensors.

You need to add unit_of_measurement attribute for it to appear as a chart.
