[Qgis-user] How to generate closed polygon from unordered set of points

[John Helly]

Hi.

I've got an unordered set of x,y pairs that I would like to plot as a line and then interactively edit the line to make a closed polygon.  I've used the points2one plug-in to make an editable line but don't seem to able to join the lines in the correct way by adding/deleting nodes.

Is it possible to do this with Qgis at all and, if so, how?

Thank you.

Cheers.
