Nov 13, 2024 · Basic Graphing in Stata Let’s start with some basic graph examples before we dive into customization. Overlapping histograms can be complicated enough with say 2 groups: 5 or 10 is usually a disaster. Let’s use the auto data file for making some graphs. It's reasonable that nearly similar distributions overlap mightly, but the graph is still likely to seem a For other histograms with varying widths, if you have Stata 7 or Stata 6 you can specify bin limits to two community-contributed programs, barplot and hist3. Histograms and Boxplots This set of notes describes how to use the computer program Stata to produce histograms and boxplots. sysuse auto. The basic command for a histogram looks like this: There are several options to consider with histograms: Stata likes to think of a histogram as an empirical approximation to a probability distribution function, but to get the kind of histogram you learned about in elementary school where the height of the bar is proportional to the number of observations in the bin, add the freq option: Aug 12, 2025 · This module will introduce some basic graphs in Stata 12, including histograms, boxplots, scatterplots, and scatterplot matrices.
