please help. making bar graph more simple with "over" options

[TaeJun Choi]

Hi, guys.

I'm a newcomers with stata, and there is some trouble in making bar graph.

My data has 46 observations, and it has numeric variable for displaying year-month.

here is some code i had run:

graph bar fluct, over(year, label(labsize(vsmall) angle(45)))    /// 
    blabel(bar, size(vsmall) format(%9.1f)    ///
    )    ///
    ytitle("Fluctuation") graphregion(color(white))

and the graph it produces:

Four problems I want to solve:

1) The x-axis labels are too many so I want to display some labels (e.g. 201910, 202010, 202110, 202210). this graph aims to show that the fluctuation along specific month by year.

2) Similar with problem 1), I want to display some bar labels only ("blabel" option).

3) some bar labels are overlapped. I want to show it not overlapping

4) I want to coloring only last one.


I attach the data here. please some help.

Welcome to Statalist, TaeJun! Please go through the advice in the Statalist FAQ, especially section 12, on how best to post questions to the list. In particular, please post a data extract using the dataex command in Stata (and not your Stata dataset), to help others respond to your query.

Please note our policy on cross-posting, which is that you are asked to tell us about it.

A short answer is that you need

twoway bar

not

graph bar

for what you want, and that you will get more flexibility with

gen mdate = ym(floor(year/100), mod(year, 100)) 

format mdate %tm

A longer answer is given within https://journals.sagepub.com/doi/10....6867X211000032 and the title

I had cross-posted this post at https://www.reddit.com/r/stata/comme...h_over_option/

and, Now I solved this problem.

I produced this graph:

It is the graph exactly what I want. I solved it an way that overlay three graph.

Here some code and data I used(check attachment):

twoway bar fluct time, barw(.6) ///
    xlabel(10(12)58, angle(45) valuelabel labsize(vsmall)) ylabel(, labsize(*0.5)) ///
    graphregion(color(white)) ///
    ytitle("") xtitle("") || ///
    bar fluct time if time == 10 | time == 22 | time == 34 | time == 46 | time == 58, barw(.6) /// 
    color(red) legend(off) || ///
    scatter fluct time if time == 10 | time == 22 | time == 34 | time == 46 | time == 58, ///
    mlabel(fluct) mlabpos(12) mlabsize(vsmall) mlabf(%9.1f) msymbol(none) mlabcolor(black) ///
    title("")
