SAS/GRAPH Statements

Example 1. Ordering Axis Tick Marks with SAS Date Values


AXIS statement options:




FOOTNOTE statement option:


SYMBOL statement options:



GOPTIONS statement options:


Sample library member: GAXTMDV1

[output from]

This example uses SAS datetime values with an AXIS statement's ORDER= option to set the major tick marks on the horizontal axis. It adjusts the position of the first and last major tick marks.

The example also uses HILOCTJ interpolation in a SYMBOL statement to join minimum and maximum values.

Set the graphics environment.. BORDER draws a border around the graph.

goptions reset=all border;

Create the data set. DOWHLC contains the high, low, and close values of the Dow Jones Industrial index for each business day for a month.

data dowhlc;
     input date date9. high low close;
     format date date9.;

Prepare the data for a high-low plot. DOWHLC2 generates three records for each date, storing each date's high, low, and close values in variable DOW.

data dowhlc2;
   set dowhlc;
   drop high low close;
   dow=high; output;
   dow=low; output;
   dow=close; output;

Define titles and footnote. JUSTIFY=RIGHT in the FOOTNOTE statement causes the footnote to be displayed in the bottom right.

title1 "Dow Jones High-Low-Close";
title2 "January, 1997";
footnote justify=right "GAXTMDV1 ";

Define symbol characteristics. INTERPOL=HILOCTJ specifies that the minimum and maximum values of DOW are joined by a vertical line with a horizontal tick mark at each end. The close values are joined by straight lines. The CV= option controls the color of the symbol. The CI= and WIDTH= options control the color and the thickness of the line that joins the close points.

symbol interpol=hiloctj

Define characteristics of the horizontal axis. The ORDER= option uses a SAS date value to set the major tick marks. The OFFSET= option moves the first and last tick marks to make room for the tick mark value.

axis1 order=("30DEC1996"d to "03FEB1997"d by week)
      label=none ;

Define characteristics of the vertical axis. LABEL=NONE suppresses the AXIS label.


Generate the plot and assign AXIS definitions. The HAXIS= option assigns AXIS1 to the horizontal axis, and the VAXIS= option assigns AXIS2 to the vertical axis.

proc gplot data=dowhlc2;
   plot dow*date / haxis=axis1
