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.

Hello,

Did you find a solution?

We have the same issue but everything works find on one QV Server... the Document has been moved to another server (for distribution) and they get the above error.

Sadly this is for a client and I don't have access to the server directly to see what is going on myself...

Thanks

Oh, sorry, I was referring to eric.careta issue

The solution for me was to add an API key to the script.js file as per these instructions:

1. To get a valid API key go to https://developers.google.com/maps/documentation/javascript/get-api-key and follow the instructions to copy the API key to the clipboard
2. Open the following file on the QlikView server in Notepad:

         C:\ProgramData\QlikTech\QlikViewServer\Extensions\Objects\GoogleMaps – Cluster\script.js

    3. Find the text below

          Qva.LoadScript('https://maps.google.com/maps/api/js?key=YOURKEYGOESHERE&sensor=false&callback=map_init')

     4. Change the key value shown to a valid key and save and close the file

     5. Refresh the page and the issue should be resolved

Hello,

the unchecked function "Single Cluster Style" doesn´t works. When the function is unchecked, none icon are displayed.

I looked into the markerclusterer.js and I realized that the others icons used to be loaded from "http://google-maps-utility-library-v3.googlecode.com/svn/trunk/markerclusterer/images/m", but this pages doesn´t exist anymore, the images were moved to github "https://github.com/googlemaps/js-marker-clusterer/tree/gh-pages/images".

I thought if I changed the images´s path my problem would be solved, but didn't work either.

Are there any solution to my problem?

Hello!

Does this extension only work with QV11? Are there any special settings required to get it to work with QV12?

Hi Alex, this is great.

This is going to sound stupid but is there a set up guide for this?

i.e. what to include and where/how?

Some extension don't work in IE Plugin Mode.

Change it to Ajax and try it?

Go to QMC and change your plugin option and see if it works
