It has random values and I can't find any equation related to it.
The values for X are {0.250 0.315 0.400 0.630 0.800 1.000 1.250 2.000 2.500
3.150 6.000} and The values for Y are {4.37% 7.98% 13.54% 50.29% 85.86%
94.39% 96.56% 98.97% 99.54% 99.80% 100.00%} total 11 values in each.
Thanks alot!

I have drawn an XYscatter chart connected with smooth lines. I want to get
the corresponding value on X axis at a know value of Y (50%) how can I do
it?
Is it possible to show the calculation by perpendicular dropping lines?
