“Ligth”

var chart =  new dhtmlXChart({
	...
        gradient:"light",
	color: "#00FF22"
   ...
})

or by function:

var chart =  new dhtmlXChart({
	...
	gradient:function(gradient){
			gradient.addColorStop(0.0,"#FF0000");
			gradient.addColorStop(0.8,"#FFFF00");
			gradient.addColorStop(1.0,"#00FF22");
		                   },
 
    ...
})

or

chart.define("gradient",function(gradient){
			gradient.addColorStop(0.0,"#FF0000");
			gradient.addColorStop(0.8,"#FFFF00");
			gradient.addColorStop(1.0,"#00FF22");
		        }
             );
