Error in graduated styling

[geguill]

Hello,
I believe the graduated analyses are incorrect; let me explain with an example.
The file Dentistes_regions.geojson contains a field named nb_dentist; the minimum value is 262 and the maximum is 9133. If I perform a quantile classification into 4 classes (outside of Geolibre), I get the thresholds 262, 1404, 2815, 4166, and 9133. However, Geolibre does not yield these thresholds: it gives 262, 1977, 3643, and 9133!
Furthermore, the resulting map appears to display 6–7 shades of blue (6–7 classes)!
The layout shows a legend with 4 classes.
