SAS.GRAPH 9.1 Reference, Volumes I and II

Example 1. Ordering Axis Tick Marks with SAS Datetime Values

Features:

AXIS statement options:

FOOTNOTE statement option:

SYMBOL statement options:

GOPTIONS statement options:

Sample library member: GAXTMDV1

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. The default unit specification for heights in the graph are percent of the graphics output area as specified by GUNIT= in the GOPTIONS statement. The GOPTIONS statement also specifies the default fonts for TITLE1 and for other text.

Set the graphics environment. GUNIT= specifies the units in percent of the graphics output area. HTITLE= specifies the height for TITLE1 text. HTEXT= specifies the height for all other text. FTITLE= specifies SWISSB as the font for TITLE1.

goptions reset=global gunit=pct border cback=white colors=(black blue green red) ftitle=swissb ftext=swiss htitle=6 htext=4;

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.; datalines;

02JAN1997 6511.38 6318.96 6442.49 03JAN1997 6586.42 6437.10 6544.09 ... more data lines ... 30JAN1997 6621.82 6481.75 6600.66 31JAN1997 6621.82 6481.75 6600.66 ;

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. HEIGHT=3 in the FOOTNOTE statement overrides the height specified by HTEXT= in the GOPTIONS statement.

title1 'Dow Jones High-Low-Close'; title2 'January, 1997'; footnote height=3 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. CV= colors the vertical lines, and CI= colors the line that joins the close values. WIDTH= controls the thickness of the line that joins the close points.

symbol interpol=hiloctj cv=blue ci=red width=2;

Define characteristics of the horizontal axis. ORDER= uses a SAS date value to set the major tick marks. OFFSET= moves the first and last tick marks to make room for the tick mark value. COLOR= makes all axis elements red. MAJOR= and MINOR= modify the size and color of the major and minor tick marks.

axis1 order=('30DEC96'd to '03FEB97'd by week) offset=(3,3) color=blue label=none major=(height=3 width=2) minor=(number=6 color=red height=2 width=1) width=3;

Define characteristics of the vertical axis. LABEL=NONE suppresses the AXIS label. The COLOR= suboption in MINOR= overrides the COLOR= option.

axis2 color=blue label=none major=(height=3) minor=(number=4 color=red height=1) offset=(2,2);

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

proc gplot data=dowhlc2; plot dow*date / haxis=axis1 vaxis=axis2; run; quit;
