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.

Thanks, Shahbaz

Still not getting the map on access point. I am not sure why this is happening. I am using qlikview version 12.

Hi Leo,

Hi All,

I have installed the Google cluster map but which is not show below. I am wondering this could be a reason for the map not shown in access point

Hi Candice,

Did get this working now? I am facing the same issue.

That extension should work fine. I guess you have not placed the extension folder in correct path on server. That could be the only reason

Check your extension folder path on server and copy the folder which I uploaded. Usually the error can be due to old IE, extension folder path misplaced or some extra security from your company. But in this case you have it all ok?

And you'll see if an extension is installed or not when you click 'Add new sheet object' in webview.

Open access point>right click>new sheet objects>Extension objects (another way to check if extension is installed in server or not)

Open the access point in Chrome and also if in IE check if you getting a tab below which says 'Content blocked'

Show or hide content option.

Thanks.

Shahbaz, if you are okay with it can I update the extension in the original post with your additions?
I don't really maintain the extension that much nowadays so any additions is helpful

I have copied the files supplied by Shabaz. The result is the same however. I keep getting the same error and the same info in the script-console:

Google Maps API error: MissingKeyMapError: https://developers.google.com/maps/documentation/javascript/error-messages#missing-key-map-error

So this solution is not working for me.

Of course Alexander you can use it. It is your extension, lol.

I just modified the .JS according to my requirements. As I needed more than 1 cluster (different color) and also I removed the 'Map Listener' script for zoom on click for 'Markers' as that view was not appropriate for many users. They just wanted state level, not street level.

Thanks.

I'm sorry, I don't know why you guys getting that error. For me it's working fine, both in desktop and server.

There is no key required for this, we do not have any option to update the API key anywhere in the script or extension
