Google Maps Extension with Cluster support.

QlikTech takes no responsibility for any code and QlikTech Support Agreement does not cover issues with this extension.

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.

Download the extension and view source code at: https://github.com/mindspank/GoogleMaps-Cluster-QV11

If you build something awesome please share it with the community!

Live long and prosper.

There has been numerous upgrades to the extension.

Now clusters now display the value of your expression and with added support to include more information in pop-up labels.

Example grayscale styled map included.

Possibility to show only a single cluster icon style if you do not want it to scale according to the number of markers in the cluster.

Alexander,

When I click on the marker, I see the infobulles but I can't select the infobulle with my mouse.

The infobulle disappears.

Thank for your help.

Thanks Alex but that doesn't appear to be working either

Yes, that is how the extension works. If you want to switch from onhover to select events instead feel free to change the the code. It's open source and available on GitHub.

Hi everyone,

Can I use this extension if my QV Server doesn't have the internet ?

Thanks

This is a GREAT extension and is creating quite a bit of stirr with some of my clients.

I am wondering if there is any documentation available. One question is just what is passed to Google. It looks as if it is only the Lat/Long coordinates and a marker. Corporate security folks are curious.

Alexander_Thor · ‎2014-12-05

Ugh, documentation... not my strong suit

All of the properties are described here however: mindspank/GoogleMaps-Cluster-QV11 · GitHub

Yeah the only thing that are passed to google are latitude and longitude.

No other data are sent over the wire, tbh you are sending more corporate data by just surfing to google.com

Thanks. Just wanted confirmation. I get the documentation thing too.

Still a great tool.

The code is open source so feel free to steal, modify, enhance to your liking.

Adding more custom requirements is usually very fast but between the marker, cluster and heatmap extensions I think I cover like 90% of the use cases for plotting points.

The cluster is a PERFECT extension to the mapping using Google. We, like most I would think have clusters and the other way just makes things too busy. Best of both worlds in the cluster extension. Good stuff.
