I am using the QGIS Cartogram plugin, but unfortunately something is not working as it should.

First, the demo works just fine. But when I want to create a cartogram with my own layer. But as soon as I click „ok“, it says "Cartogram creation cancelled by user“.

Do you have a clue, what I'm doing wrong? What am I canceling?

  • Could you please add which version of QGIS you are using? I can confirm this works for QGIS 2.8.2-Wien for Windows 7. – Joseph Aug 20 '15 at 14:38

Are there zeros or null cells in the desired collumn of the attribute table? I had this problem last week and solved adding a different value to these cells

  • +1, you are right in that it gets cancelled if zeros or NULL values are present. – Joseph Aug 20 '15 at 14:49
  • It looks like the development version has fixed this by providing more informative error messages: github.com/informeren/qgis-cartogram/issues/4 – Phil Mar 8 '16 at 16:07
