Hello, Say I have an edge property (of type double) with values ranging from 0.0 to 1.0. I want this value to be set as the alpha for my edges or at least be used as the offset with the gradient option in the graph_draw function. The idea is that for edges with stronger weights, I can reduce the alpha. (Edges weighted at 0.0 will disappear.) How can I make that happen? Using graph_draw(..., gradient=[values, 0, 0, 0, 1.0]) will not work, as the 0th index in the gradient option list must be a value from 0.0-1.0, and not some set or list or properties. There's got to be a way to do this, though. It's simple enough; I'm probably just missing something.
