Change the attributes for graph style specific fonts. The STYLE statement adds to the child styles the style element GraphFonts, which also exists in the parent style. All the style elements that use the user-defined attributes that GraphFonts defines use the attributes specified in the STYLE statement, not those specified in the STYLES.DEFAULT style. Because the FROM option is specified, GraphFonts in the Science style will inherit all of the style attributes from GraphFonts in Styles.Default, except those that specifically specified in Science. Note:   Instead of the one that is used in this program, you could have used the following STYLE statement :

style graphfaonts from graphfonts;

style GraphFonts from _self_/                                                    
         "GraphValueFont" = ("Verdana",10pt)                                  
         "GraphLabelFont" = ("Verdana",14pt,Bold);
