Venn Diagram chart

[#1]

Hi Guys,

This is first time i'm working on extension objects, I have a requirement where i have to create Venn diagram chart in Qlikview. Please share me your ideas on it. This Venn Diagram chart should worked for N series of circles(Dynamic Chart)

Hi, Dee.

QlikView doesn't have Venn Diagrams.

However, you can look for Google API extension which you can pull in. (just search for google api venn diagram). The downside of this though is that it relies on Google supporting this. As it gets pulled in as an image you don't have the full range of QlikView functionality you would expect from a chart.

Regards,

Neil.

Try using google API. Refer this document Venn Diagram in Qlikview using google chart api

Google API will be the way to go, but the only pitfall here is that it allows for only three circles. Not sure I if there is anything else that would allow for N circles, but I would be curious to know if there is something out there.

Best,

Sunny

Hi,

I guess it should be possible without extensions or external plot apis to create a Venn diagram using a scatter chart and some expressions to calculate bubble positions and sizes.

hope this helps

Wow, this looks much better than Google Api's version of the Venn Diagram. I am amazed how this method has never been mentioned on the community before.

Thanks for sharing this Marco Wedel

Best,

Hi Marco,

Do you have expressions to calculate bubble positions, in case we have buble sizes and also we know the intersection rates for bubbles? For example, let's say

B1 = 100, B2 = 80, B3 = 20, B1B2 = 80, B1B3 = 20, B2B3 = 20 and B1B2B3 = 20

Thanks,

Is there way, we can so the value as well for each area of the Vann diagram?
