Bug report #6841
Variable Jenks classification in QGIS
|Affected QGIS version:||master||Regression?:||No|

When I re-classified the bins using Jenk's classification, the bin values change substantially.
Nothing else changes: I just clicked "Classify" and every time a slightly different result emerged.
This is strange behaviour (Jenk's classification is not probabilistic, but requires a certain number of iterations I belive http://en.wikipedia.org/wiki/Jenks_natural_breaks_optimization ).
To see this behaviour, please see this video:
Is this behaviour repeated on other versions of QGIS?
Any ideas why it's happening?
