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.

Various fixes.
2014-01-09
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.

Added custom marker support. Now you can specify a url for an custom marker. Accepts all major image file types.
Cool extension, thanks a lot.
Have a quick question - say I have three locations that I want to show on the map, all quite far from each other, and the value involved is just a simple count. I can achieve this easily enough but the icon showing up is the red position marker that shows up on Google maps, but what I'd prefer is the cluster marker that shows up in the original post in this thread, which I would like to colour code depending on the size of the count. If I've explained that clearly, is it possible to do this?
Thanks again for the extension.
Hi Daniel,
It sounds like you should be using my marker extension instead.
It wont display a number but you can specify custom markers conditional depending on your data.
You can find it at
http://github.com/mindspank
If it still doesn't fit your needs let me know and I can probably whip a custom solution for you.
Kind Regards

I am using the this esxtension which is very cool however my popups are not coming out correctly in the popup contents field I have
'Name - '& [Property Name] & '<br>' & 'Address - '& [Property Street] &', ' & Suburb & ', ' & City & '<br>' & 'Owner - '& [Owner Name] & '<br>' & 'Type - '& [Property Type] & '<br>' & 'Total Area - '& [Area SQM] & ' SQM' & '<br>' & 'Total Rental PA - '& '$'& ([Lease Total Rent PA]+[Lease Opex PA]+[Lease Carpark Rent PA])
But what I am getting on the desktop version is
However once it is on accesspoint what I am getting is
Does anyone have any idea why or what i might be able to do to get the popup message i want
Hi Alex
I know this has been asked previously but i can't find a response anywhere, does this extension use a free google map key and if so do I need to code one in somewhere?
Thanks for any advice

There is no difference in how the Server and Desktop would render the extension.
Are you sure you are using the same version of the extension in both the Desktop and Server?
Hi,
No Google Maps has stopped using keys altogether so one is not needed.
If you are a current Google Enterprise customer you might want to include your ID and white list the traffic in the Google Management Console but that's about it.
Thank you for the responses.
I will check the versions of the extension as they may be different.
I've added,
Lng | Lat | Desc | Speed Limit |
-73.987587 | 40.740993 | 1 madison ave | 100 |
-73.980126 | 40.761697 | 1301 avenue of americas | 200 |
but it shows in balloon symbols instead of circles in yellow color. Can anyone explain me why it shows in that style, why not in circle.
It will only group markers into clusters if you have more then a number of points within a single area. Try zooming out.
Kind Regards
