My apologies for such a basic question. I'm using WA Pro on a Mac, 10.9.3.
When I plot a graph, it uses only a small fraction of my screen area, I would like to display the graph larger.
Enabling Interactivity causes the zoom icon to gray out (green arrow).
I can enlarge the graph (purple arrow), but this causes the graph to enlarge, but not the Wolfram Alpha viewing window... ie I have to scroll about to view the graph.
Thanks for you help.
