HISTOGRAM Statement
Creates a histogram that displays the frequency
distribution of a numeric variable.
| Interaction: | The HISTOGRAM statement can be combined only with DENSITY statements in the SGPLOT procedure. |
| Note: | The range of the response variable is automatically divided into an appropriate number of bins. |

Summary of Optional Arguments
Histogram options
specifies the X coordinate of the first bin.
specifies the bin width.
specifies how boundary values are assigned to bins.
specifies whether the area fill is visible.
specifies the appearance of the area fill.
specifies the number of bins.
specifies whether outlines are displayed for the
bars.
specifies the scaling that is applied to the vertical
axis.
specifies that the midpoints of the value bins are
used to create the tick marks for the horizontal axis.
Plot options
specifies how many times observations are repeated
for computational purposes.
specifies a label that identifies the histogram
in the legend.
specifies a name for the plot.
specifies the degree of transparency for the histogram.
assigns the response variable to the secondary (top)
horizontal axis.
assigns the calculated values to the secondary (right)
vertical axis.
Optional Arguments
- BINSTART= numeric-value
- specifies the X coordinate of the first bin. Use this option in
conjunction with the BINWIDTH= or NBINS= options to specify bins.
If neither BINWIDTH= nor the NBINS= option is specified, the system
determines the number of bins. If the BINSTART value results in excluding
the entire range of data, it is ignored and the default BINSTART value
is used. Default:The default value is determined by the system.
- BINWIDTH= numeric-value
- specifies the bin width. The system determines
the number of bins. The bins always span the range of the data.Default:The default value is determined by the system.Interactions:
This option is ignored if the NBINS= option is also specified.
- FILL | NOFILL
- specifies whether the area fill is visible. The FILL option shows
the area fill. The NOFILL option hides the area fill.Default:The default status of the area fill is specified by the DisplayOpts attribute of the GraphHistogram style element in the current style.Interactions:Specifying FILL also hides any visible outlines.
If NOFILL and NOOUTLINE are both specified, then both options are ignored.
- FILLATTRS= style-element | (COLOR= color)
- specifies the appearance of the area fill. You
can specify the color of the fill by using a style element or by using
the COLOR= suboption. You
can specify colors using the same color schemes that are supported
by
SAS/GRAPH software. For more information, see Color-Naming Schemes in SAS/GRAPH: Reference.Default:The default color is specified by the Color attribute of the GraphDataDefault style element in the current style.Interaction:This option has no effect if you specify the NOFILL option.
- FREQ= numeric-variable
- specifies how many times observations are repeated for computational purposes. Each observation is repeated n times for computational purposes, where n is the value of the numeric variable. If n is not an integer, then it is truncated to an integer. If n is less than 1 or missing, then it is excluded from the analysis.
- LEGENDLABEL= “text-string”
- specifies a label that identifies the histogram in the legend. By default, the label of the response variable is used.
- NAME= “text-string”
- specifies a name for the plot. You can use the name
to refer to this plot in other statements.Note:The name is case-sensitive. When you refer to the specified name in other statements, you must use the same exact capitalization.
- NBINS= numeric-value
- specifies the number of bins. The system determines
the BINWIDTH= value. The bins always span the range of the data.The procedure attempts to produce tick values that are easily interpreted (for example, 5, 10, 15, 20). The procedure sometimes adjusts the location of the first bin and the bin width accordingly. As a result, the number of bins shown in the plot might not exactly match the number specified with NBINS=.Default:The default number of bins is determined by the system.
- OUTLINE | NOOUTLINE
- specifies whether outlines are displayed for the
bars. The OUTLINE option
shows the outlines. The NOOUTLINE option hides the outlines.Default:The default status of the outlines is specified by the DisplayOpts attribute of the GraphHistogram style element in the current style.Interactions:Specifying OUTLINE also hides the fill color.
If NOOUTLINE and NOFILL are both specified, then both options are ignored.
- SCALE= COUNT | PERCENT | PROPORTION
- specifies the scaling that is applied to the vertical
axis. Specify one of the
following values:
Default:PERCENT
- SHOWBINS
- specifies that the midpoints of the value bins are used to create the tick marks for the horizontal axis. By default, the tick marks are created at regular intervals based on the minimum and maximum values.
