Creating scatter plots in SAS is a simple process that can be done in a few steps. First, you need to enter the data into SAS and then create a scatter plot using the SGPLOT procedure. You can customize your scatter plot by changing the color, size, symbol, and other aspects of the plot. Additionally, you can add labels and a title for clarity. Finally, you can export the plot as an image file or save it as a SAS dataset for further analysis.
You can use the following methods to create scatter plots in SAS:
Method 1: Create One Scatter Plot
proc sgplot data=my_data;
scatter x=var1 y=var2;
run;
Method 2: Create Scatter Plots by Group
proc sgplot data=my_data;
scatter x=var1 y=var2 / group=var3;
run;
The following examples show how to use each method with the following dataset in SAS:
/*create dataset*/ data my_data; input team $ points rebounds; datalines; A 29 8 A 23 6 A 20 6 A 21 9 A 33 14 A 35 11 A 31 10 B 21 9 B 14 5 B 15 7 B 11 10 B 12 6 B 10 8 B 15 10 ; run; /*view dataset*/ proc print data=my_data;
Example 1: Create One Scatter Plot
The following code shows how to create a scatterplot for the points and rebounds variables:
proc sgplot data=my_data;
scatter x=points y=rebounds;
run;
The x-axis displays the values for the points variable and the y-axis displays the values for the rebounds variable.
Note that we can also add a title to the plot and modify the appearance of the markers within the plot to make it more aesthetically pleasing:
title "Points vs. Rebounds";
proc sgplot data=my_data;
scatter x=points y=rebounds /
markerattrs=(symbol=CircleFilled size=12 color=purple);
run;
Example 2: Create Scatter Plots by Group
title "Points vs. Rebounds by Team";
proc sgplot data=my_data;
scatter x=points y=rebounds /
markerattrs=(symbol=CircleFilled size=12)
group=team;
run;
This plot allows us to quickly visualize the relationship between points and rebounds for both team A and team B.
