For datetime and duration data, the value of 'BinWidth' can be a scalar duration or calendar duration. Width of bins, specified as a scalar. For example, in the following statements, the NORMAL option displays a fitted normal curve on the histogram, the MIDPOINTS= option specifies midpoints for the histogram, and the CTEXT= option specifies the color of the text: proc univariate data=Steel; histogram Length / normal midpoints = 5.6 5.8 6.0 6.2 6.4 ctext = blue; run; SAS Histogram with Normal Curve.

As we have seen with a histogram, we could draw single, multiple charts, using bin width, axis correction, changing colors, etc. However, in bar charts, all bars are the same width in the bar and the height shows the difference. Before you proceed to sketch or insert a curved line graph on this chart, you must mark the midpoints of each bar in the frequency distribution like this: These mid points can be drawn manually if you are displaying your information on a hard copy chart.
