Plotting inequalities #28

Open aantthony opened 13 years ago

Areas should be shown when functions like y>x+1 are plotted.

I'm not sure how to plot an inequality for something like http://graph.tk/?theta<20_exp(-r^2)+1 because the current algorithm won't work for http://graph.tk/?theta<20_exp(-r^2)+2 and http://graph.tk/?theta<20*exp(-r^2)+3...

Would it be reasonable to just draw a line to the point on the edge of the screen that corresponds to the theta value of the last plotted point on the end of the line, and then depending on what quadrant that is in, to just fill around the edges like you would for http://graph.tk/?theta%3C1 ?
