Is it possible to make QGIS generate a legend that is based only on the field visible in composer?
There was a ticket marked as resolved five months ago with this question but it doesn't divulge the solution! http://hub.qgis.org/issues/3121
There are other questions appearing to ask this but I can't find the solution within them. A workaround I'm using at the moment is to save a new vector layer based on a selection of the field of view and plotting a legend from that.
Is there must be a more sensible way?
