Weight example

[fungiboletus]

Hello.

Yes a weight example is missing. But it should no be very different than categories. By default, each marker has "1" as weight but you can change the value with marker.weight = newvalue

Reusing the random.10000-categories example, it's something like this :

for (var i = 0; i < size; ++i) {
    var marker = new PruneCluster.Marker(59.91111 + (Math.random() - 0.5) * Math.random() * 0.00001 * size, 10.752778 + (Math.random() - 0.5) * Math.random() * 0.00002 * size);

    marker.category = Math.floor(Math.random() * Math.random() * colors.length);

    // Set a random weight between 1 and 3
    marker.weight = Math.ceil(Math.random() * 3);

    markers.push(marker);
    leafletView.RegisterMarker(marker);
}

I would like to provide better examples including this feature, but I am not sure if this feature is very useful.

Merci pour votre réponse rapide. La fonctionnalité de pondération est très utile pour les data que je souhaite publier : ici une base de 1.2M de points représentative du commerce de proximité en France agrégée par segment de rue. Chaque point étant noté/pondéré en fonction du nombre et de la surface des commerces présents dans chaque segment. En fait, je souhaite afficher des clusters pondérés sur les long/lat et afficher la somme des pondérations sur chaque marker.

J’ai vu par défaut la pondération égale 1.
J’ai testé sur votre exemple (random.10000-categories example) qui prends bien en considération les poids sur les X et Y mais cela n’a pas d’effet sur l’affichage des comptages de chaque marker. Il faudrait afficher la variable totalWeight à la place de la variable population mais cela à des impacts sur l’icône d’affichage en particulier lorsque l’on ajoute une analyse par catégorie. Il y a donc un peu de tunning à faire sur le code pour une fonctionnalité de pondération complètement satisfaisante.

Votre travail est fantastique !

In English :
Thank you for your quick response. The weighting feature is very useful for the data that I want to publish: 1.2M points of the retail shops in France aggregated by street segment. Each point/street segment weighted according to the number and the importance of business present in each segment. In fact, I want to display the weighted long / lat and the sum of the weights on each marker clusters.

I saw the default weighting equal to 1.
I have tested with your random.10000-categories example. That is OK for the weighted calculation of the long/lat but this has no effect on the display of the counting on each marker. It should display the variable “totalWeight” instead of the variable “population”. But this has some impacts on the icon display especially when combining with an analysis by category. So there could be a bit of tuning on the code for a completely satisfactory weighting feature.

This work is fantastic! I have tested another 2M non weighted point data and it is working fine.
