I have a bme280 tenp/pressure/humidity sensor reporting via MQTT. I graph them with gplot. Sofar, so good. The problem is pressure is reported in Pascals. I could modify the code that reads the me, but I'm hoping there is a way to app,y a scale to each reading as the gis made. made. For example multiplying Pascals by 0.00296 gives in hes of mercury, or dividingb by100 gives hPa,
Sorry for the duplicate.
