I’m on Grafana 8.5.1. I’ve a dashboard visualizing temperature, max and min values in three panels for the time period. Now I want to visualize the trend of the past hour (independent of time period) with an up or down arrow in a separate panel. Ho to do this?
Not sure what your datasource is, but using InfluxDB, I would write a query to compare the current temp vs temp 1 hour ago. If the value is positive, display 1. If the value is negative, display 0. In Grafana, paste the query and use value mappings with emojis to display an UP or DOWN arrow in a Stat panel.
