st: plotting conditional indirect effect with confidence bands

I'm hoping someone can help me with stata code for producing a graph that plots the conditional indirect effect with confidence bands. I just completed a moderated mediation analysis using Preacher et al.'s (2007) SPSS macro, and have attempted to use SigmaPlot to do the graph portion as Preacher did. No success. The program is new to me and I don't plan on wasting too many hours trying to figure out what I need to do.

Preacher, K., Rucker, D., & Hayes, A. (2007). Addressing moderated mediation hypotheses: Theory, methods, and prescriptions. _Multivariate Behavioral Research_ _42_(1), 185-227.

I have the component values needed: the point estimate as well as the second order variance (as page 202 of Preacher et al. highlights). I just need some advice from someone a bit more versed in Stata than I am.

Anyone?  Anyone?
