Pie charts are also used to display qualitative data. between statistical textbooks and Statas own documentation. For example, to graph gender we can use the following Stata command: The Stata command is:īar charts are frequently used to display nominal or ordinal data. Also see G-2 graph export Export current graph G-2 graph manipulation Graph manipulation commands G-2 graph save Save. The advantage of the one-part construction is that you will not forget to save it. For example, to compare total cholesterol levels between men (coded as 1) and women (coded as 0) click on the By option and select male to display the data by gender. The advantage of the two-part construction is that you can edit the graph between the time you rst draw it and save it. Graphics > Box plotīox plots provide a five number summary of the dataīox plots are especially useful for comparing two or more plots. The median is lower than the mean indicating right skewness and the skewness is > 0, a positive number confirming data is slightly skewed toward the right. The graph export command can be used in Stata to save a graph as an Encapsulated Postscript file for use in applications like LaTeX. You can confirm this by running descriptive statistics. The histogram and the overlaid normal curve shows that the total cholesterol data is slightly right skewed. The option normal specifies that the histogram be overlaid with an appropriately scaled normal density curve. In the Command Window and press Enter to run the command. Since this is a continuous variable we can graph histogram or a box plot. Let’s graph the variable total cholesterol. Qualitative/Categorical data on the other hand are most frequently displayed using a bar chart and less frequently using a pie chart.Īll graphs can be accessed from Stata’s Graphics menu on top of the screen. Quantitative data can be displayed using histogram, box plot, or a scatter plot. and save order sort foreign gen sortorder n sort randomly so Stata will sort. The choice of the type of graph to use depends on the type of data available. 2: graph 13) Use the merge command to merge this data with the Stata. Stata for Unix(GUI) users should use the name() option if there is more than one graph displayed to ensure that the correct graph is exported (see Technical note for Stata for Unix(GUI) users). graph newvar1p1 newvar2p1 newvar2dx 3.3 Advanced plotting of the eects of the variables The praccum command is a very powerful tool that in combination with other commands allows us to plot probabilities from models with interaction terms. Type graph export lename.sufx in the Command window. To see the codesheet read my blogpost on Descriptive Statistics. Select File > Save Graph., and choose the appropriate Save as type. I will use the Framingham dataset – framingam.dta – that can be downloaded HERE.
#Stata save graph how to#
In this blogpost I will demonstrate how to create five types of graphs in Stata: Histogram, Box plot, bar chart, and a pie chart.
