Delete feed from Multigraph

Is it possible to remove a feed from a visulisation used for a multigraph? Seems you can add feeds but not delete one.

There should be a little [X] to click to remove a feed:

Ah, OK thanks. The dark grey on a slightly lighter grey background did make is less obvious than it might be.

Cheers.

I checked to see if my changes had impacted this, thankfully it hadn’t.

I’m still very new to all of the HTML bits and have worked out how the ‘x’ is shown, but cannot see how to change it from mid grey to black. I’ve tried opacity settings, changing colours etc, but to no avail.

If anyone else knows what needs to be changed, then please let me know and I’ll add this in to the code being tested.
