You cannot use the WEIGHT statement with the HISTOGRAM statement. Of course, the biggest difference between the PROC FREQ bar charts and the PROC SGPLOT bar charts are the washed-out colors in the PROC FREQ graphs. See the section Output Data Sets for information about the output data sets produced by Jan 11, 2022 · Notice that the two histograms share an x-axis, which makes it easy to compare the points values between the two teams. In SAS, the FREQ procedure can be used to analyze and summarize one or more categorical variables. The second example uses proc freq to produce a bar chart and cumulative frequency graph in addition to the frequency table for ses. We can see how the frequency (density) varies across the bins. The bar chart can be generated with PROC FREQ. The normal option creates a superimposed normal curve. No need to use Proc Freq. Figure 3.
