Specify attributes for the GraphWalls element. This STYLE statement is applied to the walls inside of the graph's axes. The GRADIENTDIRECTION is set to Xaxis, meaning the gradient is going left to right. The ENDCOLOR, defined in Gwalls, which is CXFFFFFF, is the final color used with the gradient. The data elements of the graph have a TRANSPARENCY of 100 percent. Because a STARTCOLOR is not specified, the beginning of the gradient is completely transparent.
