Creating Single-Cell Graphs

The SGPLOT procedure creates single-cell graphs with a wide range of plot types including density, dot, needle, series, bar, histograms, box, and others. The procedure can compute and display loess fits, polynomial fits, penalized B-spline fits, and ellipses. You can also add text, legends, and reference lines. Options are available for specifying colors, marker symbols, and other attributes of plot features. You can customize the axes by using axis statements such as XAXIS and YAXIS.

Plot statements can be combined to create more informative plots and charts. The following example shows two series plots that are overlaid in a single graph. Each plot is assigned to a different vertical axis. Data labels have been added for easy reference.

title "Power Generation (GWh)";
proc sgplot data=sashelp.electric(where=
  (year >= 2001 and customer="Residential"));
  xaxis type=discrete;
  series x=year y=coal / datalabel;
  series x=year y=naturalgas / 
      datalabel y2axis;
run;

The following example creates a graph with a histogram, a normal density curve, and a kernel density curve.

proc sgplot data=sashelp.class;
  histogram height;
  density height;
  density height / type=kernel;
run;
