Description
i am using a shp and a joined dbf-table with some demographic data
calculation of class breakes with style = graduated returns wrong breake values.
see attached *.png
the value-range within the field BEV91_P_H is from 0.000 to 646.4222
type of the field is real / 19 / 11
lower value of the first class starts with 5.00 instead of 0.00
either this breake value is wrong
or a class with breaks 0.000 - 5.000 is missing
... consequently the objects with values < 5.0 are missing in the map display.
this problem was already existing in 1.7 !
which is remarkable since classification is a key issue of cartography within a gis tool

also this one - no problem in qgis master !
(like #7842)
just a remark: the problem obviously did only occur with data from joined tables.
as soo as i saved the layer incl. the joined data to a new shp erverything was ok with the classification.
nice idea to demonstrate the potential of non commercial software ...
thx again
