Graphic equation in a cell

[edneco]

Hello everyone..... This is my first post here and I´m not sure if this is the right place to put this question.....

I have a file connected to web and collect some values in a row. This row is conected to a graphic. More data I have, better is the tendency line..... It´s not a estatic graphic, so the graphic equation is always changing when data is collected.

The most difficult part to me is that I need that graphic equation in a cell in a way that allow me to make some calculations with this equation.

I don´t know if it´s needed a VBA code or there is another way to do this.....

I must "warn" you that my knowledge about VBA code is minimum......

If some one can elucidate me on yhis, I thank you very much.......
