Examples
Example 1: Testing a GOPTIONS Statement
Features:
-
GOPTIONS statement
-
GTESTIT procedure
Sample library member: GITTGOS1
This example illustrates how you can use the GTESTIT procedure to confirm the settings specified on a GOPTIONS statement. In this example, the GOPTIONS statement enlarges the size of the elements in the graphics output by decreasing the number of columns from the default number of columns for the device, resets the font to the default, and specifies a limited colors list.
Set the graphics environment. HPOS= selects 45 columns. VPOS= selects 25 rows. FTEXT= resets the font to the default font. COLORS= can determine the colors displayed in picture 1 and listed in the LOG, and the value of NCOLORS=.
goptions hpos=45 vpos=25 ftext= colors=(blue red green);
Display the first picture of the GTESTIT procedure.
proc gtestit picture=1; run; quit;
Example 2: Displaying, Changing and Verifying the Colors List for a Device Driver
Features:
-
GOPTIONS statement
-
GOPTIONS COLORS= option
-
GTESTIT procedure
The colors that SAS/GRAPH uses for the elements of a graph are determined, in order of precedence, by:
-
The presence in a GOPTIONS statement of options that control the color of elements (for example, GOPTIONS CTEXT= to control the color of text).
-
The COLORS= option on a GOPTIONS statement
-
The default color list for the device driver for which the graph is being prepared.
For more information on the order in which SAS/GRAPH chooses colors, see Defining and Using a Colors List on page 93
You can use PROC GTESTIT to display the default color list for a device driver. For example, the following procedure displays the default color list for graphs prepared for the ActiveX control.
goptions reset=all device=activex; proc gtestit picture=1; run; quit;
Running this procedure shows the default color list for the device ActiveX, as seen in the following output from PROC GTESTIT:
D=ACTIVEX B=1200 R= 43 C= 83 P=256 H= 13 W= 9 MAX= 0 D=8000000000000000 RF=8000800000000000 S=0000000000000000 OPTS=3500304009280008 NCOLORS= 10 Backgroung color = WHITE Color 1 = BLACK Color 2 = RED Color 3 = GREEN Color 4 = BLUE Color 5 = CYAN Color 6 = MAGENTA Color 7 = GRAY Color 8 = PINK Color 9 = ORANGE Color 10 = BROWN Ratio = 0.74941 Hsize = 8.42 Vsize = 6.31 F=1
The following procedure uses the COLORS= option of the GOPTIONS statement to change (temporarily) the color list for the device driver ActiveX. Then, it invokes PROC GTESTIT to verify that the color list is changed. The color list is changed at most for the duration of the SAS session. Use the GDEVICE procedure to change the color list permanently.
goptions reset=all device=activex colors=(red, green, blue, yellow); proc gtestit picture=1; run; quit;
The following output from PROC GTEST shows that the color list for ActiveX has changed:
D=ACTIVEX B=1200 R= 43 C= 83 P=256 H= 13 W= 9 MAX= 0 D=8000000000000000 RF=8000800000000000 S=0000000000000000 OPTS=3500304009280008 NCOLORS= 4 Backgroung color = WHITE Color 1 = RED Color 2 = GREEN Color 3 = BLUE Color 4 = YELLOW Ratio = 0.74941 Hsize = 8.42 Vsize = 6.31 F=1
The following code resets the color list for the ActiveX device to the default, and then reissues PROC GTESTIT to verify that the colors have been reset:
goptions colors=() device=activex; proc gtestit picture=1; run; quit;
The following output confirms that the default color list has been re-established:
D=ACTIVEX B=1200 R= 43 C= 83 P=256 H= 13 W= 9 MAX= 0 D=8000000000000000 RF=8000800000000000 S=0000000000000000 OPTS=3500304009280008 NCOLORS= 10 Backgroung color = WHITE Color 1 = BLACK Color 2 = RED Color 3 = GREEN Color 4 = BLUE Color 5 = CYAN Color 6 = MAGENTA Color 7 = GRAY Color 8 = PINK Color 9 = ORANGE Color 10 = BROWN Ratio = 0.74941 Hsize = 8.42 Vsize = 6.31 F=1
