I need a service that will allow me to draw a chart line by hand and generate data points for what I drew. This might sound crazy, but I need some data (preferably in CSV output) that will only approximately show value X at time Y and I do not want to go and produce these values by hand. I only have to know how it will flow along. Anyone know how to actually accomplish this?
So, I would actually want to draw a line on a graph, and then get the output (X + Y) from that line I drew in a (preferably) CSV.
