Here our home spot is at 600-650 meters altitude we fly at 600-900 meters height so When I turn on the GPS.Alt in the view the number is so high that all the other graphics get almost like a line around the 0 point. It is especially inconvenient when we have to analyze VTOL transitions. So please can you add a way that FlightPlot detects where the 0 ground is and provide in some way Relative Altitude Visualization instead of the GPS.Alt in real numbers.\r\n\r\n![gpsalt](https://cloud.githubusercontent.com/assets/12617619/13336765/8ab91bd0-dc20-11e5-8455-bfbff25c2fc1.png)\r\n\r\n\r\n\r\n"}}
