[Qgis-user] How should the Scalebar unit settings affect?

[Wesley Roberts]

Which version of QGIS are you using? I notice you have been posting about
the new print composer on your blog and was wondering if you were using a
new version of QGIS.

I have a method but it is a little bit of a hack / work around using two
maps on the print composer. I don't have time now to explain but if you
don't find a solution I will see what I can send you.

Briefly, add a second map to your print composer once your main geographic
/ wgs84 map is complete (except for the scale bar), make sure it is the
same size as your original (width and height). Lock the layers etc for your
main geo map.

Now, go back to your QGIS main window and change the projection (bottom
right corner) to your projected coordinates, DONT change the extent.

Once this is done go back to your second map (in the print composer) and
update the extents of the map. Now add a scale bar to the projected map
window and select the units etc. If all goes well you can now use the
projected scale bar on your original map.

My explanation is a little dodgy, hope you can make sense of it.
