Example: Defining the Background Color of the Legend Area

The following request makes the background color of the legend area tan:

GRAPH FILE WF_RETAIL_LITE
SUM DISCOUNT_US GROSS_PROFIT_US REVENUE_US MSRP_US
BY PRODUCT_CATEGORY
ON GRAPH PCHOLD FORMAT JSCHART
ON GRAPH SET LOOKGRAPH VBAR
ON GRAPH SET STYLE *
INCLUDE=IBFS:/FILE/IBI_HTML_DIR/javaassist/intl/EN/ENIADefault_combine.sty,$
*GRAPH_JS
"legend": {"backgroundcolor": "tan"},
"series": [
	{"series": 0, "color": "lightgreen"},
	{"series": 1, "color": "coral"},
	{"series": 2, "color": "lightblue"},
	{"series": 3, "color": "burlywood"}
	]

*END
ENDSTYLE
END

The output is:

The following request applies a linear gradient that transitions from bisque to ghostwhite to the legend background area:
