Excel tip: Instant in-cell graphs

Lifehacker has posted a Really cool hack:

Fooplot is neat!

Dheera Venkatraman has released Fooplot, a new website that plots any function, and supports Google Maps-style panning around. (from Ajaxian).



I think this is pretty neat. The fooplot.com/yourfunctionhere is cool.

I couldn't plot a circle though, it only plotted a semi-circle. Same with a parabola.

I would love to see the following features:

• Plot for y = constant, x = constant
• Chart Save-as
• Support multiple plots using the fooplot.com/yourfunctionhere URL. Currently it supports only one equation.
• Upload XML data.
