Visualizing Categorical Data: gdispla

The gdispla macro ( get gdispla.sas)

Device-independent DISPLAY/NODISPLAY control

It allows for the fact that for direct output to the display device, the required GOPTIONS are NODISPLAY or DISPLAY, whereas for output to a GSF, GIF, or EPS file, the options are GSFMODE=NONE or GSFMODE=APPEND. It is usually used with the PANELS macro, or other programs which produce multiple plots and then join those plots in a template using PROC GREPLAY. Some multi-plot programs use the GDISPLA macro internally.

Usage

Parameters

SWITCH

A string value, OFF or ON.

IML

Specify any non-blank value to use the GDISPLA macro within SAS/IML.

Global parameters

 %let devtype=eps;

DEVTYP

String value, the type of graphic device driver. The values EPS, GIF, CGM and WMF cause the macro to use the GSMODE option; the value DEVTYPE=SCREEN causes the macro to use the DISPLAY or NODISPLAY option. All other values are ignored.

Example

%include vcd(gdispla);        *-- or include in an autocall library;
%let devtype=SCREEN;

  %gdispla(OFF);
  proc gplot;
     plot y * x;
     by group;
  %gdispla(ON);
  %panels(rows=1, cols=3);
