[Qgis-user] symbology shapefile polygons: equal intervals classes

[Azzurra Lentini]

Dear all,
I have a shapefile of polygons and I would like to classify it (in
symbology) using for example 6 classes with these values
0-10
10-20
20-30 etc.

The field to classify has values from 0 to 63.4 (decimal numbers).
And I would like to have the result in graduated colors.

Till now I have been using:
*Symbology*/graduated
*Method* color and I give a color ramp
*Mode: *equal interval and I give the number of classes,
the problem is that  I must insert the classes manually (one by one)
otherwise the numbers are not entire.

Please can you suggest me any other faster method? (for example for the
raster I can give minimum and maximum as integer number -in this case it
would be 0 - 60- and I can specify the number of classes and automatically
Qgis tematize the raster with equal intervals (all the classes and not one
by one).

Thank you Azzurra
