Charting Frequencies with the CHART Procedure
Types of Frequency Charts
By default, PROC CHART creates a frequency chart in which each bar, section, or block in the chart represents a range of values. By default, PROC CHART selects ranges based on the values of the chart variable. At the center of each range is a midpoint. A midpoint does not always correspond to an actual value of the chart variable. The size of each bar, block, or section represents the number of observations that fall in that range.
PROC CHART makes several types of charts:
vertical and horizontal bar charts
display the magnitude of data with the length or height of bars.
display the relative magnitude of data with blocks of varying size.
pie charts ...
