Programmatically Create Survival Curves

i am using vb.net / asp.net

my team created a web application (research database for cancer center)

i am wondering if anyone has an idea about drawing survival curves programmatically

i searched every where and couldnt find any idea

you have to study the equation of kaplan meier thoroughly and then try to do it using vb.net or c# datatable, then chart it using mschart control.

Please check this article
