light-vector attribute

Used By:Graph elements

Set the vector of where the light used to shade the graph is coming from.

The default is 1,0,0, which makes the light appear to come from the right side of the graph. A value of -1,0,1 would put the light to the left and in front of the graph, while a vector of 0,-1,0 would put the light directly underneath the graph, for a strange result indeed.

The light is assumed to be coming from an infinite distance away in the specified direction, so don't worry about the length of the vector.

Set a strong shadow coming from the upper right corner of the graph

piegraph { light-level:100; light-vector:10,5,0; }
