There is no documentation on expressions except any examples on MapLibre website. What would be these different stuffs ? Thanks |

Answer about this question : I generated symbology with MapBox Studio, in order to have exact syntax. There may be a bug here.

Hi,
I am working on datae and I am trying to create a symbology using expressions. Problem is at 'circle-color', I have indicated that white is a default color, but in my app, the rendering is black.
I don't understand why, this is my code.
Thank you very much for your help,
Sylvain
const date0 = ["<=", ['get', 'annee'], 1904];
const date1 = ['all', ['>', ['get', 'annee'], 1904], ['<=', ['get', 'annee'], 1945]];
const date2 = ['all', ['>', ['get', 'annee'], 1945], ['<=', ['get', 'annee'], 1975]];
const date3 = [">=", ['get', 'annee'], 1975];
const daten = ["==", ['get', 'annee'], null]; // possible that the problem is here (with coalesce ?)
