Dear all,

I was wondering if there is someone who can help me with regards to my bar graph.
With the following code I created the graph shown below:


graph bar (sum) PSPP CSPP CBPP3 ABSPP, over (Date_APP_M, label(angle (90) labsize(small)) relabel(1"Mar"2" "3" "4"Jun"5" "6" "7"Sep"8" "9" "10"Dec"11" "12" "13"Mar"14" "15" "16"Jun"17" "18" "19"Sep"20" "20" "22"Dec"23" "24" "25"Mar"26" "27" "28"Jun"29" "30" "31"Sep"32" "33" "34"Dec"35" "36" "37"Mar"38" "39" "40"Jun"41" "42" "43"Sep"44" "45" "46"Dec"47" "48" ")) ///
stack over (Date_APP_Y) ///
ylabel(, angle(0) labsize(small)) ///
ytitle("EUR (billions)") ///
note ("Source: History of APP redemptions, ECB website", size(vsmall)) ///
legend(label(1 "PSPP") label(2 "CSPP") label(3 "CBPP3") label(4 "ABSPP"))
Now I am stuck with a few questions:

(1) Can I add a line variable that shows the average monthly purchases of these four programs? I know I can add a straight line, but the line I want to add changes its value over time (from 60 to 80 back to 60, to 30, to 15). As far as I know (and I just started using stata, so I might be wrong), I can only add bars and lines in one graph with two-way. But as I am using groups, I cannot use a two-way graph?

(2) How do I change the ylabel so that it adjusts in steps of 10? So "0 10 20 30 40 50 60 70 80 90", in stead of "0 20 40 60 80".

(3) How I can reposition the labels of the x-axis? As it is now, the months under the bars don't correspond with the value of bar. As the first bar shown is supposed to be March, but now this is not the case.


Thank you for taking the time to read this.

Best,
Lisanne
