Is there any way to manually classify Graduated Data in Qgis. In ArcGIS I always used to apply first the natural breaks method to find adequate group sizes for good visual interpretation. Afterwards I adjusted slightly the group-size to have nicer breaks.
So if for example breaks from jenks classification would have been:
1-12 13-21 22-42 43-50
than I could change them manually to:
1-10 11-20 21-40 41-50
by just clicking into the corresponding rows and changing the values.
Anything similar in Qgis?
Besides: Has anybody idea why Qgis always finds different group sizes any time I push on Jenks?
