# Gap between bars in bar graph

Below is a worked example:

The data set I used is auto.dta. The commands I used in a do-file is:

```
sysuse auto, clear
graph bar (mean) price turn mpg weight, over(rep78)
set obs 75
replace rep78=2.5 in 75
graph bar (mean) price turn mpg weight, over(rep78, relabel( 3 " " ))
```

If you would like to know more on Stata graphs, you will find the book __A Visual Guide to Stata Graphics, 3rd Edition__ very useful.
