I would like to classify shapefile values using graduated style in QGIS, but instead of using the default mode of classification (e.g.natural breaks with values range 0-10, 10-20, 20-30), I would like to set the values range to 0-10, 11-20, 21-30. Is it possible?
You can use Rule based classification, i.e. create a rule for each of the intervals. But be careful with the use of > greater than and >= greater than or equal.
To put this more into perspective, consider the following example:
value > 0 AND value < 10
value >= 10 AND value < 20
If you don't use the
>= for the second interval and just use
>, and you happen to have a value of exactly 10, this value will be omitted from the classification.
Is your field integer or real?
