Qlik Sense Heatmaps

Tue, 17 Nov 2015 12:54:33 GMT

Hi there,

I would like to create a heatmap within Qlik Sense. My requirements:

- Based on X, Y coordinates

- Possible to use my own SVG / PNG. I have a floor plan of a shopping mall either in PNG or SVG I would like to use.

- It should be a separate layer on top of the SVG/PNG, which is not filling predefined SVG / KML areas.

So the result should look something like this:

Thanks!

Hi Jveldhoen,

- Based on X, Y coordinates

- Possible to use my own SVG / PNG. I have a floor plan of a shopping mall either in PNG or SVG I would like to use.

Firstly, convert the PNG image you have into a SVG which can be done using Inkscape. Make use of this generated SVG path and build a visualisation using D3.(This will solve the first two question you have)

Now coming to the third question:

- It should be a separate layer on top of the SVG/PNG, which is not filling predefined SVG / KML areas.

So the result should look something like this:

Create an other layer of SVG over the underlying sketch and use fill property to colour this layer , based on your measure or any specific condition.

Hope this helps!

Hi Sangram,

Thanks for your reply. I already used Inkscape to build a SVG, this works. I also used the SVG Reader (Qlik Sense SVG Reader) to fill the polygons with a colour. But now I want to take it a step further so that I can get gradients of colours like I showed in the picture. You may be right that I need to develop my own D3 extension to do this.

Any other thoughts?

Hi Jveldhoen,

I think building an extension for this requirement is the best way to go.Let me know if you need any help in building an extension.

Thanks and Regards,

Sangram Reddy.

Hi,

you can do this perfect with NPGeoMap (officiall they have only a qlikview extension, but you can already get the sense beta version). There you can even build graphic drill downs,..

bye
