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.

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.

Hello,

I got similar problem - extension is installed and running both for desktop and server. However, I can use custom markers on desktop but not on server thru AP. I tried both extension and document server locations in Custom URL (which work all fine for desktop) to avoid user rights problems:

%ProgramData%\QlikTech\QlikViewServer\Extensions\Objects\GoogleMaps - Cluster

%ProgramData%\QlikTech\Documents

%ProgramData%\QlikTech\SourceDocuments

but custom marker doesnt show (under the same user logged to AP).

Any hint?

That's not a valid url. You are referencing a file system resource and not serving them up over a webserver.

Either you could host them with whatever web server you are using to host accesspoint, qvws/iis/apache, or go upload them to www.imgur.com if that's easier.

[Alexander_Thor]

Yes that would be doable but not with this extension. If your floor plan is available as a svg file I would recommend the svgMap extension which is built for that purpose.

It also happens that we use the same technique to visualize our Qlik offices and employee locations so it's absolutely doable but the Google Maps extension is not the correct tool for that.

OK, thx. I don't have IIS installed there and I hope I'll find in QVS manual what URLs are made and what folders are linked for them.

http://localhost/qlikview is not directing to Program Files\QlikView\Server\QlikViewClients\QlikViewAjax

[Alexander_Thor]

Love the extension.  For some odd reason though the Markers are not working in ajax on the qlikview server.  They work fine in my client but for some odd reason they do not work on the server.  I tried referencing custom markers on the server and then also tried to use googles marker colors and still nothing.  I have the latest extension.  The only thing I have changed is referenced https instead of http in the js file for the maps so I did not get a security warning in the app.
