You can create multiple graphs by including secondary sort dimensions (fields).
By default, the number of graphs created depends on the number of values in the fields you designate in the sort (BY, ACROSS) phrases. You can change this default using the GRMERGE parameter:
Multiple graphs can be displayed in either merged format or in columns. For details, see Merging Multiple Graphs and Displaying Multiple Graphs in Columns.

By default, when you create a graph that has multiple BY fields, or a BY and ACROSS field, multiple graphs are generated. You can merge these graphs into a single graph or into multiple merged graphs.
To do this, use the SET command GRMERGE.
SET GRMERGE={ON|OFF|ADVANCED}
where:
Turns on the merge graph option.
Turns off the merge graph option. This is the default.
Turns on the advanced merge option. This option uses three parameters to determine how to merge the graphs:
Note: The sum of the sort fields used by GRMULTIGRAPH, GRLEGEND, and GRXAXIS must equal the number of sort fields in the graph request.
The syntax for the GRMULTIGRAPH, GRLEGEND, and GRXAXIS parameters is:
Specifies how many sort fields (0 through 2) to use to break the output into multiple graphs. The outermost sort fields are used to separate the graphs. When n is greater than zero, this is similar to GRMERGE=OFF, but allows an additional sort field.
Specifies how many of the remaining outermost sort fields (0 through 2), after the ones used for GRMULTIGRAPH, to add to the graph legend. When n is greater than zero, this is similar to GRMERGE=ON, but allows an additional sort field.
Specifies how many of the remaining sort fields (1 through 3) to display on the X-axis. When n is greater than 1, this creates nested X-axes.
The following illustrates a graph with two horizontal, or X-axes, categories (PRODUCT_ID and PACKAGE_TYPE) that have been merged.
SET GRMERGE=ON GRAPH FILE GGORDER SUM UNIT_PRICE ORDER_NUMBER ACROSS PRODUCT_ID BY PACKAGE_TYPE END
The output is:
The following example generates a vertical bar graph that separates the outermost sort field (REGION) onto separate graphs, distinguishes the next two sort fields (ST and CATEGORY) by combining them on the graph legend, and places the CATEGORY sort field on the X-axis:
GRAPH FILE GGSALES SUM DOLLARS BY REGION BY ST BY CATEGORY BY PRODUCT WHERE CATEGORY EQ 'Food' OR 'Gifts' WHERE PRODUCT EQ 'Coffee Pot' OR 'Biscotti' OR 'Mug' ON GRAPH SET GRMERGE ADVANCED ON GRAPH SET GRMULTIGRAPH 1 ON GRAPH SET GRLEGEND 2 ON GRAPH SET GRXAXIS 1 ON GRAPH SET LOOKGRAPH VBAR END
The first graph is for region Midwest. The legend distinguishes State-Category combinations by color, and the PRODUCT sort field is repeated on the X-axis for each State-Category combination:

When you create an OLAP graph that has multiple BY fields, or a BY and ACROSS field, multiple graphs are generated. You can merge these graphs into a single graph.
To do this, use the SET command OLAPGRMERGE.
SET OLAPGRMERGE={ON|OFF}
where:
Turns on the merge graph option. With this setting AUTODRILL is disabled for the graph.
Turns off the merge graph option and creates a separate graph for every value of the outer sort field. OFF is the default value.
The following OLAP request against the EMPLOYEE data source has two BY fields. To merge the graphs, the SET OLAPGRMERGE=ON command is issued:
-OLAP ON SET GRAPHEDIT=SERVER SET OLAPGRMERGE=ON TABLE FILE EMPLOYEE SUM SALARY BY DEP BY LAST_NAME ON TABLE SET PAGE-NUM OFF ON TABLE NOTOTAL ON TABLE PCHOLD FORMAT HTML ON TABLE SET HTMLCSS ON ON GRAPH SET HAXIS 300 ON GRAPH SET VAXIS 100 ON TABLE SET AUTODRILL ALL ON TABLE SET OLAPPANE TABBED ON TABLE SET STYLE * INCLUDE = endeflt, $ LEFTMARGIN=0.500000, RIGHTMARGIN=0.500000, TOPMARGIN=0.500000, BOTTOMMARGIN=0.500000, $ TYPE=REPORT, TOPGAP=0.000000, BOTTOMGAP=0.013889, $ ENDSTYLE END

When you create a graph that has multiple BY fields, or a BY and ACROSS field, multiple graphs are generated. You can display these graphs in columns.
To do this, use the SET command GRWIDTH. GRWIDTH may be set to any value between 0-512. The default is 0.
SET GRWIDTH=nn
where:
Is the number of columns in which to display multiple graphs. This may be any value from 0-512. The default is 0.
All values from 1-512 will display graphs in an HTML table with the corresponding number of columns. The default value of 0 will display the graphs one under the other in a Java applet.
The following illustrates how to set the number of columns in which you wish to display multiple graphs. In this example, the graphs are set to display in two columns.
SET GRWIDTH=2 GRAPH FILE GGORDER SUM UNIT_PRICE ORDER_NUMBER ACROSS PRODUCT_ID BY PACKAGE_TYPE END
The output is:
