ODS style templates, or styles, control the overall look of your output. An ODS style template consists of a set of style elements. A style element is a collection of style attributes that apply to a particular feature or aspect of the output. You can specify a value for each attribute in a style. See Chapter 21: Statistical Graphics Using ODS in SAS/STAT 13.2 User's Guide, for a thorough discussion of ODS Graphics.
To create your own style or to modify a style for use with ODS Graphics, you need to understand the relationships between style elements and graph features. This information is provided in the ODS Graphics documentation at http://support.sas.com/documentation/onlinedoc/base/ . You can create and modify style templates with the TEMPLATE procedure. For more information, see the section "TEMPLATE Procedure: Creating a Style Template" in the SAS Output Delivery System: User's Guide. Kuhfeld (2010) also offers detailed information and examples.
A predefined ODS style template named NETDRAW is available for the NETDRAW procedure. You can use the template to maintain a consistent appearance in all graphical output produced by the procedure.
To change the current style, specify the STYLE= option in an ODS destination statement. The specified style is applied to all output for that destination until you change or close the destination or start a new SAS session. For example, the following statement specifies that ODS should apply the NETDRAW style template to all HTML output:
ods html style=netdraw;
To disable the use of graphical styles, specify the SAS system option NOGSTYLE.
The parent style template for the NETDRAW style is the DEFAULT style. Table 9.7 lists the style elements (in bold) and corresponding attributes specified in the NETDRAW style. The table also indicates which, if any, PROC NETDRAW options or graphics options (in a GOPTIONS statement) can be used to override the value of a style attribute.

Figure 9.9 demonstrates features of the NETDRAW graphical style. The diagram in the figure is the first output from Example 9.11.
If the SAS system option GSTYLE is in effect (this is the default), then the default values of certain PROC NETDRAW options can depend on the current ODS style template. Table 9.8 lists these PROC NETDRAW options and lists the order in which PROC NETDRAW searches for each option’s default value. The order assumes that the GSTYLE system option is in effect; if that is not the case, then the steps that refer to ODS style templates are ignored. Names with arguments indicate style elements and attributes of the current ODS style template. For example, "GraphAxisLines('Color')" refers to the Color attribute of the GraphAxisLines element.
