"bring to front" or "bring to top" type of functionality?

[Divya Mistry]

Is it possible, perhaps via a script, to select a set of edges and bring them to the front so that they are visible above all others? I have a dense circle layout where a set of edges are hidden under other edges. I would like to make sure that those edges get drawn above all the rest, so that when I want to export a graphic with specific selection, they are never hidden. Is it possible to do so? Maybe there's a script I could write to do that? If so, I'd appreciate someone pointing me to the right direction.

Thanks.

Hi Divya,
    I'm afraid not.  We added Z ordering for nodes, but not edges.  The only thing I can suggest is to select those edges -- that should cause them (and only them) to be redrawn, so they'll be on top.  When export them as a graphic, though, they will be redrawn, unfortunately.  You might try to set the opacity of all of the other edges so that they are semi-transparent.  That should help to highlight the edges you want.

Ok. Thanks for the ideas. I'll see what I can produce.

Would cyREST be of service here? It enables a python/R application to access Cytoscape data and display model. See cyREST app in app store.

Barry, I saw the CyREST api. I wondered if I could draw specific edges on top of other ones. Gor example, ask it to select specific edges, then draw all other ones, then draw the selected ones. Might be worth investigation. Nothing in the documentation for CyREST says that the order has to be as user-intended. It might still redraw to its best optimized case when exporting the output. I'll get back to you if that ends up working. My initial gut feeling says that this approach won't make any difference to final image export.

I think you're right. Scooter, too.

In the end, cyREST affects the data model but not the rendering engine. So, if the rendering engine can't float edges to the top, cyREST can't make it.

Sorry for the diversion.

Hi Scooter,
I selected the edges but they don't seem to be redrawn at the top of the image. Any suggestions?

Best,

Sathvik
