Hi,
I would like to know how to suppress the decimals of the km field in a Gantt chart. The field used to import the data was "Début(distance)"
The image below illustrates my issue.

The field "Coût total" does not have the same problem because it was imported with a text field. The same cannot be done with km so that the data are sorted correctly (from smallest to largest).
The Gantt chart is organised as shown in the image below.

Thank you for your inputs.
Best regards,
Ivo
