As it uses 3D accelerated graphics it can easily display more then a million values and still maintain real time interaction and decent FPS. It provides functions like positive, mono, stereo or multiple display type of graphs, configureable colors, making a selection, adding markers, animated zoom in and out, automatic amplitude adjusting, customized axis text, etc.
