If I'm looking for an "accurate" result, where the polygons get reasonably correctly sized relative to the data column being used, how do I know how many iterations to run? I've already seen that it looks like I need to run more iterations in order to get a reasonably-looking distorted result when the low to high range of the data is separated by several orders of magnitude. But what I don't know is how to determine how many iterations I "should" run in order for my result to be mathematically accurate. Does running too many iterations endlessly exaggerate differences between polygons? Is there a way to know what the correct number of iterations I should run is?

Just cloned this into /usr/share/qgis/python/plugins and it ain't working ("no metadata file"). Happy to work on a fix because it's a great plugin when working. Any suggestions?

I have joined a .csv file to the data in my .shp file (well, the .dbf, obviously), and I can see the data in the attribute table, but the field doesn't show up on the list of available fields in the drop down to choose a data field in the cartogram creator plugin.

I don't know enough about QGis to install the plugin manually; could you publish it in the official repository? (Or is it published and my QGis 2.4 just doesn't see it?)
Or add a guide on where to clone this repository to?

Perhaps I'm doing something wrong, but...

Hi,

launching cartogram on either Qgis 2.0 or 2.4 on Fedora 20, I get the following error:

the cartogram plugin has been unzipped to the "/home/nao/.qgis2/python/plugins/cartogram_creator" directory.

Have you any idea of what is going wrong ?

regards,

When I put these files in /Users/me/.qgis2/python/plugins/cartogram-master and start QGIS, and select Cartogram Creator from the plugins menu, the side panel says
"This plugin is broken
invalid syntax"
