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.

Hi Alexander,

I'm trying to use the google maps cluster extension object. By default it's zoomed in, so all I see is the marker and zoom tool. I don't see the map unless I manually zoom out. I tried changing the corresponding JavaScript to include (say zoom: 10) as part of mapOptions, but it didn't work.

Please advise.

QV Version 11.20.12577.0 SR8 64-bit Edition (x64)

Browsers: Chrome 37.0.2062.124 and Firefox 32.0.3

Thanks,

After modify many times, i can see map for browser.

I suspect the size map, because, change for 600x600, and nothing filter in customers, the map show me.

And using size 400x400 and nothing filter in customers, don´t see. But, if select some customers, the map is show me.

Thanks for the help.

Hi Alex, my end users use Citrix, which IE 9 is installed. When they open the app (Ajax) with this cluster extension, the map just shows blank. There is no problem on IE10. Is there any way to fix it?

Hi Alex

Thank you for this extension it will make my clients very happy, I do however have one question, in the popup text is it possible to add a line break, I have tried chr(10), chr(13), '%OA' and <b> but none of them are creating the line break as expected.

Thanks in advance for any guidance

It uses HTML syntax so do a
for a line break

Kind Regards
