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

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 Alex,
I'm using a simple count like Count(Distinct ClientCode) in a cluster map but even the zero results are showed in the map (clusters with "0" value). Is there a way to hide zero or null values?
Hi Alex
This map is amazing really helpful! I have a question regarding the display in AJAX for some reason when developing it works perfectly. it shows referrals from various areas with the correct number displayed in the grouped circles see screen shot.
But when I try to access this via QlikView access portal the numbers seem to change instead of showing how many referrals it displays how many postcodes are there. see image below.
The first image is how I thought it would of displayed in AJAX have you come across this before or know a work around?
Thanks
No worries I sorted it. I had to paste all of the files from the user extension folder to the QlikView server folder and it worked
Thanks
One of the expressions was resulting zero for all field values. My mistake.
Hi Alex
I have used the your Google map extension and it worked like a charm.
But there is one issue , in my data model i have countrywise LAT LONG coordinates and they are displayed perfectly on the maps with Red pins , but as soon as user clicks the Pins , map got blank.
What could be the possible reason for this.

Hi Alexander, this extension is great!

HI,
I can get the Map to work on my Desktop, and also when opened via the Server. When trying to access it through accesspoint it will only work using Ajax and not IE Plugin? Do you have any advice for this?
Thanks very much!
