Narrow range of graph using cibar

[Mike Murphy]

I am trying to plot a chart with confidence intervals, where I know the variable is bounded such that it is always >=0. However, for some cases my CI is negative, causing the chart to include negative values for y, as in the following (nonsense) example:

sysuse auto
replace price = price-4000
cibar price, over1(rep78)

Adjusting the yscale does not work, as this only allows me to expand the scale. Is there anyway to narrow the y-axis without subsetting the data?

you don't say how you are computing the CIs but that appears to be your problem; if you provide more information, maybe someone can help; -cibar- is a user-written command, as the FAQ asks that you explain, never having used it, I don't know whether it is computing your CIs or just taking up CIs calculated in some other way; in general, however, Stata will not allow you to "hide" data by restricting the range of a graph so you need better CIs
