How to label point of intersection of X and Y in bar graph

[Ashish Bandhu]

Dear Statalist users

While preparing the bar graph, I want to label the point of intersection of X and Y (origin) in the bar graph as the first entry of the date variable (Starting Date) which is 25feb2022, and at last/end of the x-axis as the last date which is 22mar2022.

Data is

end
format %td date
label values site1 site
label def site 1 "A", modify
label def site 2 "B", modify
label def site 3 "C", modify

The code I have used is

graph hbar (count), over(site1) over(week1) bar(1, fcolor(navy)) blabel(bar) ytitle(Count) title("My Name is Manoj") xlabel(min(date1) max(date))
but it showing me error

As the help explains

graph hbar draws horizontal bar charts. In a horizontal bar chart, the numerical axis is still called the y
axis, and the categorical axis is still called the x axis, but y is presented horizontally, and x
vertically.

Something like this is more flexible:

bysort site1 week1 : gen count = _n 

twoway bar count week1, by(site1, note("")) xla(1/5) base(0) barw(0.8)

Hi Nick,
Thank you for prompt help, but, twoway bar does not solve my purpose. The expected graph is for reference. I don't know why xtitle does not work work in bar command.which I think can solve my purpose.

Thanks
