Graphing - tline by dummy

[Toby Jones]

Hi all,

I want to add shaded bars to my graph using tline. I notice that the stata help file only indicates how to add bars by explicit dates input. I have too many to input manually and wish to add them by a variable which is a dummy corresponding to a date.

Thanks

twoway (line SPFrespondentsexpect1519 TIME, ylabel(0(20)60)) (line CCI_EA19 TIME, yaxis(2)), ylabel(90(10)105, axis(2)), tsline SPFrespondentsexpect1519 CCI_EA19, tline(dummy_I_wish_to_add)

Shaded bars seemed ambiguous but the magic word "recession" allows a guess at what you mean. (Cox's Third Law of Statalist is that to a good first approximation we don't work in your field so you may need to explain as if we are ignorant.)
