ASCII/UTF Graphing Calculator. Is able to scan/calculate a plane from specified expressions & start to end coordinates, and draws/prints its graph. Supports custom resolution, "line" width, zoom, anti-aliasing and scan offset (antialias, zoom & width are all controlled by resolution (step)).
The expressions to graph are specified at xprA and xprB variable blocks. The default expressions here are equivalent to "y = sin(x)".
x0 and y0 are the initial coordinates (start of scan). x1 and y1 are the final coords. "step" is the "resolution", small = detailed. x and y are just the "mutable coords" that are used when scanning and frequently change their value based on the stepping.
