Google Maps Extension with Cluster support.

Please review Googles license agreement before you put this into production.

Introduction

This is a QlikView extension object that integrates Google Maps Javascript API V3 and a third party library called MarkerClusterPlus into QlikView.

Load a set a coordinates into QlikView and visualize them together with this extension. The clustering feature is create when you have alot of data points and needs to group/cluster them together for greater visability and performance.

The maxzoom property defines at what zoom level you want your markers clustered. The grid size property controls how big or small cluster grid size you want.

You can either use the extension 'as is' or use it as a base to further customize it to fit your needs.

Hi,

When we give filter at one lat long (Google map cluster) then its go on max zoom leve how we control that please suggest.

[Alexander_Thor]

Every marker/position is pushed into something called a bounds object. This keep tracks of all the markers and calculates the bounds between the furthest points.

The map is then zoomed to fit into those points. So if you only have a single marker on screen/selected the map will automatically zoom to the appropriate location.

There is two ways to control this, either you do some checking and don't call map.fitBounds(latlngbounds) unless your checks evaluate to something.

Or you could set a maximum zoom level to prevent the map to zoom past that point. That is configured in the map options literal, see the google maps docs for more information.

Feel free to fork the project and modify the behavior, https://github.com/mindspank/GoogleMaps-Cluster-QV11, but it is not something that I will be including from my end.
