Thanks to all who replied -- none of the responses were perfect ;-)

Svend's comes closest; however, the idea of using -contract- and then reloading the data prior to dozens of graphs is not very appealing.

Thanks again,

Rich

I need to produce a sizable number of bar graphs for a client. The

client wants the y-axis to be labeled as, e.g., "15%" rather than as,

e.g., .15. The range of proportions for these graphs varies quite a bit

(from a max of less than .05 to a max of over .2) so I don't want to

force them all to be the same.

After seeing a graph, it is easy enough to use the ylabel option to get

what I want. Given that I am generally willing to live with Stata's

automatic choice of tick marks, is there a way to automatically get

labels in the form I want (e.g., "15%") rather than the way Stata wants

(e.g., .15)?

======================================================================

You could -contract- the dataset, determine the maximum percent, and

create a macro containing a label corresponding to that. Here is an

example:

-------------------------------------------------------------

sysuse auto , clear

contract rep78 , percent(pct) nomiss

local pmax = r(max)/r(sum)

if `pmax' < .05 {

local ylab `" 0 " 0% " 1 " 1% " 2 " 2% " 3 " 3% " 4 " 4% " 5 " 5% "

"'

}

else if `pmax' < .10 {

local ylab `" 0 " 0% " 2 " 2% " 4 " 4% " 6 " 6% " 8 " 8% " 10 " 10% "

"'

}

else if `pmax' < .20 {

local ylab `" 0 " 0% " 5 " 5% " 10 " 10% " 15 " 15% " 20 " 20% " "'

}

else {

local ylab `" 0 " 0% " 10 " 10% " 20 " 20% " 30 " 30% " 40 " 40% " 50

" 50% " "'

}

graph bar pct , over(rep78) ylabel(`ylab')

-------------------------------------------------------------

Hope this helps

Svend
