Such app would be super useful for Edge 520, because Garmin "forgot" to add option for x,y-axis scale, therefore everthing looks flat and there is no chance to get idea how incoming terrain gonna look, unless we ride up really long steep mountain, hill. There are just default values 60m elevation for each 400m in elevation graph on Edge 520 firmware and that cannot be change, what makes elevation Graph on Edge 520 useless. Such app would be highly appreciated.
