Gradients from thresholds are too harsh (temperature)

Good evening.

I’m using a USB SDR to connect to an old external temperature/humidity sensor and am feeding it the updates to Influx on a Raspbery Pi.

I thought I’d make a simple weather station to colour temperatures in the graph so that cold is blue and red is hot. I have set a number of custom thresholds in the panel but there seems to be no way for there to be a smooth gradient between threshold colours which means the transitions between temperatures are just really harsh.

Is this something that I can do with Grafana? Grafana seems to do everything that I want, and show everything I want, but I can’t work out how to do a smooth gradient between thresholds?

Don’t use thresholds, but set min/max and use suitable color scheme:
