I want a few things in my charts:

1) How can I tell Stata that the position of the line corresponds to a specific date? I need a line for peak and a line for trough in the chart. As long as date has peak or trough =1, a line would be created in the chart. So for example if may 1953 has peak =1, I would like that indicated in the chart by creating a vertical line in the chart and the date indicated in the chart and if sept 1954 has trough = 1, a line and the date indicated in the chart too.

2) Are there ways to shade the area between the lines? So I would like to see the area between a peak and a trough shaded grey: between the lines the area is shaded grey.


Any help in this area would be appreciated. Thanks!
