问题
I am having trouble having two instances of cytoscape setup on same webpage. I have two window vars "cy" and "cy2" that are being used for different graphs. They are functionally different graphs and need to be available on different parts of the page. I wanted to know how to get that setup correctly?
When I look at page elements, the one not showing has the width and height of the underlying canvases set to 0 by cytoscape.js. Can you please help me to understand what is being initialized wrong or how these values can get set like that.
Thanks gmania

Take a look at the multiple instances demo: http://js.cytoscape.org/demos/310dca83ba6970812dd0
Also make sure you set dimensions properly in your CSS for each container. If you specify a div with zero size, then the internal Cy canvases will match.
