Origin Ver 2015.b9.2.196 and Service Release (Select Help-->About Origin):
Operating System: Win7

Hi everyone!
Help me please. I can't fit my graph It's work with cern-root, but unfortunately with Origin I can't do it.
My function is - y = A*(1-[exp{-(x-D)/B}]) + C
Bound is:
0.00000000001<A<0.01
0.000001<B<0.01
-0.1<C<-0.1
-0.1<D<-0.1

The Example of my data https://yadi.sk/i/R7bw8N3Bj-kyFA

C and D must make no sense given
-0.1<C<-0.1
-0.1<D<-0.1

Some parameters need fixing during the process. Given reasonable initial values, the result is A = 2e-5, B=3.57801e-5, C = 0.09939, D = 0.00133
