Graph changing x-axis label

[Jay Rege]

Hi,
I´m creating the follwing graph in a loop

 graph bar commitment_amount_usd_constant if group_recipient_sector == `i', over(year)

However, the resulting Graphs look pretty squeezed, therefore I would like to change the labeling of the x-axis
I tried the following Option

xlabel(1973(5)2013)

to Display every fifth year, which did not work, furthermore I would like to Change the lables from horizontal to vertical.
Any help would be greate!

Such graphs have no x axis.

This is just a bar chart of means over time. I wouldn't do it this way.

Here is some technique. Absent a data example, I just call up a sandbox:

webuse grunfeld

* mess! 
graph bar invest, over(year)

* more flexible 
egen mean = mean(invest), by(year)
twoway bar mean year
twoway bar mean year , barw(0.8) ytitle(mean investment)

Wanting to change time axis labels to vertical is a sure sign that there's a much better way to work.

In your case, you would want to start with something like

 
 egen mean = mean(commitment_amount_usd_constant) , by(group_recipient_sector year)

Depending on how many sectors you have, a single graph may even be possible.
