Andy's Graphing Calculator

It produces standard mathematical Cartesian graphs as standard HTML and PNG onto your microSD and available for further reuse in your report or anything you desire. Even for the unlikely case you forgot to insert a memory card it will also function without it using internal area. If you intend a simple scalar use, please get Advanced Calculator (if requiring special definition such as Pascal's Triangle) or set x to [number, number] for simpler mathematical systems.

I am now aware of the fact there's sometimes EmptyStack error, it isn't so really. What happens is that a continuous mathematical ranges must be divved up for processing by a computer. The number of range parcels are less than expected due to minute technical details, should be 1 or 2 missing points at the edges.

The app also creates the graph fast, your graph files will be in /graphs/graph-.html and same other file with the extension .png The is in fact not random but always on the increase as time goes by so each file is stamped with time as its filename and a greater number equals newer plotting.
