Dear all

1) I'd like to put a vertical line on the x-axis in my Stata Graph. I need this line to show when the Brexit occured (31.January.2020) to better describe the development before and after Brexit.
2) Furthermore I'd like to show my y-axis values in a 45° angle because they have to many digits. I know I can switch it in the "Graph-Editor" settings, but does anybody know if there is a appropriate command for it, so I can put it in my Do-File?

This is my Do-File so far
Code:
*Data import*


import excel "/Users/nicolasstappen/Desktop/Nico/Studium/Master/5. Semester/Masterarbeit/Daten/tESTall Data in one file nur ab 2019_MN.xlsx", sheet("Trade values") firstrow case(lower)

** Exceltabelle mit Daten bis August22:
//import excel "/Users/nicolasstappen/Desktop/Nico/Studium/Master/5. Semester/Masterarbeit/Daten/tESTall Data in one file nur ab 2019.xlsx", sheet("Trade values") firstrow case(lower)

format %100.0g tradevalueus // um e's wegzubekommen
format %100.0g tradevaluemilus // um e's wegzubekommen

replace tradevalueus=round(tradevalueus,1)

graph twoway line tradevaluemilus zeit if tradeflow=="export" & partner=="germany", title("Germany Export") name(graph1) c(L) //Graph
graph twoway line tradevaluemilus zeit if tradeflow=="import" & partner=="germany", title("Germany Import") name(graph2) c(L) //Graph

graph combine graph1 graph2

graph twoway line tradevaluemilus zeit if tradeflow=="export" & partner=="germany", title("Germany Export") name(graph1) c(L) //Graph
graph twoway line tradevaluemilus zeit if tradeflow=="import" & partner=="germany", title("Germany Import") name(graph2) c(L) //Graph

Thanks in advance and best regards
