Description

Hi I tried to used the "Pretty Breaks" classification mode.

It enden up with classes:

0-100
100-200
200-300
....
600-700
700-782

It is quite pretty but the max value in my shape file is 15718??

So these large values just disappear from my map!

It is a very big shape file with 1.5 million records.
If I save a smaller selection as a new shape file and use "Pretty Breaks" I get the right classes.

Hello, bug triage...

this bug is fixed, at least on QGIS 2.13 master. I can have 1,6 million of points and the Pretty Breaks option of the graduated renderer make classes with all the values of my layer.

I am closing this bug.
