polygon minus polygon (polygon with hole)

[Riccardo]

Hi everyone,

I have to render a polygon minus another polygon like that... 

How can I do in Qlik Sense with GeoJSON  sintax?

Is it a multi-polygon with particolar syntax? I think it is a multy-poligon with a master polygon and two polygons in minus with the master...

Thank you,

Regards

[Riccardo]

I think I found the solution here: https://tools.ietf.org/html/rfc7946#appendix-A.3  but it seems to not work...

Here is an example:

1. Go to http://geojson.io and put on the right the polygon attached at the bottom of this post

2. See the same polygon in Qlik Sense GeoAnalytics

geojson:

{
"type": "Polygon",
"coordinates": [
[
[
11.260128021240234,
43.76151727392542
],

Try in the native mapchart, it has better support for multipolygons with holes.

Thanks,

What differences are there between the GeoAnalytics Extension and the Native Map charts?

I have to put into Map:

- 3 Area Layer

- 2 Bubble Layer

Can I use Native Map Charts instead of GeoAnalytics Extension?

Yes, by now the native map chart has almost the same visualization features.

There are some missing but we are adding features every milestone. Custom toolips and image symbols are coming (most likely) in spring 2020.

Thanks,

Patric

According with GEO-1474, this is a bug and it will fixed on Release February 2020.

For the meantime we will use the Native Map.

Thanks
