I would like to graduate from a column of mine with decimal numbers. For this I want to apply the Jenks discretisation and exclude zero. I tried this, but it didn’t work…
Do you have any idea to do that?
You need to switch to Rule-based styling to remove 0 value from the classification. You can use Graduated classification first to classify your data using the desired column as it is and using
Mode: Natural Breaks (Jenks) as you can see below:
However, to remove the 0 value you need to switch to Rule-Based classification, and as you can see in the following image, the highlighted rule shows the
ColumnName >= Value. In this example
New_ID >= 0.000
You need to change it to
New_ID > 0.000 by removing the equal
= sign. But in this case the polygon with the value equal zero will disappear.
