I wish I had time to have built that part myself! I'm leaning heavily on open source plugins like these [1][2]. The gradients are representative of elevation. So red = highest points along the trail and green = lowest points. Where you see sharp gradients from green to red is where the steepest slopes are. There is slope graph that can be setup in the plugin configuration.
