How to overlay a specified value w/ CIs atop a regression in graph builder (see image)

I found a figure I somehow generated years ago and am at a loss trying to replicate it (see attached). I can generate a similar graph using inverse prediction of a probit analysis comparing dose response of several groups but I am not able to edit the graph (specifically to thicken the line width). 


Does anyone know a way for me to build this figure in graph builder where I can have more creative control? I have exported the predicted formulea for each group but have no idea how to overlay my predicited dose at a specified probablity (50%) with confidence intervals for each group in a way similar to what is generated by the inverse prediciton function. 


Thanks in advanced for any input.
