How i can trace a curve from spreadsheet , but it doesnt belong to any function and not polyline as in chemistry titration between acid vs base graph between pH vs volume
if you have two columns with values you can select them and right clicking create a list of points
then you can use Fit (one of them, there are a lot) for geting a function
only i want to join the points together but not a segment connection
something like that
perhaps spline() is enough for you
yes that what i want thanks .........
Maybe the beta-function is useful.
search also with google: geogebra titration
