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.

Hey Mihir,

Yes that would be possible. The cluster icons are actually images so scaling them dynamically without loosing image quality is going to be hard.

But controlling the number in the image and color should be doable. I'll look into it and get back to you.

Hi,

I am opening Google map cluster but still get a stack overflow error. How can I address this?

Also, how can I plot data points on my map corresponding to certian latitude and longitude values? Can I only do this with google cluster or can I also do it with the normal Google maps?

Thanks.

I'm attaching a JavaScript file.

What you have to do is convert the Google Maps - Cluster into .zip

Then replace the .js file in the folder with the one I'm attaching.

Convert the .zip back to .qar and double "qlik" to install.

The current default action on clicking a single marker is that the map zooms to that location and just displays it.

But I can change it to do almost anything that JavaScript allows.

It should work, but let me know if there's an issue.

Edit:

Please like if this works!
It took a lot of effort and time.
