bars? Say that you were looking at writing scores broken down by race and ses. You might want to graph the mean and confidence interval for each group using a bar chart with error bars as illustrated below. bar chart with error bars r This FAQ shows how you can make a graph like this, building it up step by

step. First, lets get the data file we will be using. use http://www.ats.ucla.edu/stat/stata/notes/hsb2, clear Now, let's use the collapse command to make the mean

and standard deviation by race and ses. collapse (mean) meanwrite= write (sd) sdwrite=write (count) n=write, by(race ses) Now, let's make the upper and lower values of the confidence interval. generate hiwrite = meanwrite + invttail(n-1,0.025)*(sdwrite / sqrt(n)) generate lowrite

= meanwrite - invttail(n-1,0.025)*(sdwrite / sqrt(n)) Now we are ready to make a bar graph of the data The graph bar command makes a pretty good bar graph. graph bar meanwrite, over(race) over(ses) We can make the graph look a bit prettier by adding the asyvars option as shown below. graph bar meanwrite, over(race) over(ses) asyvars But, this graph does not have the error bars in it. Unfortunately, as nice as the graph bar command is, it does not permit how to insert error bars in excel mac error bars. However, we can make a twoway graph that has error bars as shown below. Unfortunately, this graph is not as attractive as the graph from graph bar. graph twoway (bar meanwrite race) (rcap hiwrite lowrite race), by(ses) So, we have a conundrum. The graph bar command will make a lovely bar graph, but will not support error bars. The twoway bar command makes lovely error bars, but it does not resemble the nice graph that we liked from the graph bar command. However, we can finesse the twoway bar command to make a graph that resembles the graph bar command and then combine that with error bars. Here is a step by step process.First, we will make a variable sesrace that will be a single variable that contains the ses and race information. Note how sesrace has a gap between the levels of ses (at 5 and 10). generate sesrace = race if ses == 1 replace sesrace = race+5 if ses == 2 replace sesrace = race+10 if ses == 3 sort sesrace list sesrace ses race, sepby(ses) +---------------------------------+ | sesrace ses race | |---------------------------------| 1. | 1 low hispanic | 2. | 2 low asian | 3. | 3 low african-amer | 4. | 4 low white | |---------------------------------| 5. | 6 middle hispanic | 6. | 7 middle asian | 7. | 8 middle african-amer | 8. | 9 middle white | |---------------

Making bar graphs in Stata may be easiest using the menus. SelectGraphics on the Mac toolbarand click on Bar chart; this will bring up http://www.reed.edu/psychology/stata/graphing/bargraph.html a window detailing the bar chart options. To include a variable in your graph, check the box next to a field and select the variable you'd like to chart from the field's drop-down menu. For more on the tabs available to most graphs using the menus, see graph menu tutorial To make multiple graphs according to a grouping variable, use the By tab. If you want a bar graph with error bars, the process is somewhat more complicated. For starters, the UCLA Website UCLA Website offers some good resources. Ultimately however, you may find it easier to do this particular graphing in a different program, such as Excel.

Xtline allows you to generate linear plots for panel data. We will show a number of examples from a data file which contains a measurement of alcohol use, alcuse, taken at ages 14, 15, and 16 for 82 children (identified by the variable id). We use Stata graph scheme s2mono, which produces plots in grayscale, because publications often require monochromatic plots." Stata Code Fragment: Creating
