Free custom curve calculator?

[shawnb]

Does anyone know if theres a free custom curve calculator?

One i can enter my drops in at certain distances out to my max range and it gives me a curve.

Thanks.

Ps im not buying another app or program. I have a few calculators but just wondering and thought it might be helpful for others as well.

If you have a spreadsheet program on your computer or tablet you can get a curve/plot

If you have a trajectory, which is basically your drops at different distances then enter the distances in one column and the coesponding drops in the column right next to the distances.
