Qlikview Associative Radial Chart
This is a chart I came across a few years ago (unfortunately I’ve no idea who created it so apologise for not showing a credit where it’s due) and thought it would come in use one day, I hope it acn be put to wider use.
What we’re showing here is relationships between products; commonly associated products are joined by a brighter line and it’s as simple as that really. However the method needed to achieve this simplicity is quite complex; I won’t try and go into it here but the trickiest part is getting the positions of the datapoints correct which involves the sin() & cos() functions.
I’d love to be able to re-work this chart so as to make the thickness of the lines relative to volume say (much like other similar non-Qlikview charts I’ve seen), unfortuntately it doesn’t seem to be possible as the ‘Line Style’ expression has no effect within a Scatter Chart (as this is). Regardless I think in the right circumstances this can be a really useful visual; especially for analysing associated and complimentary products within orders are a customers overall purchase history.
The .qvw can be downloaded here: https://docs.google.com/open?id=0B0nQ9tZcY4wza2JsRHU2TVJRRXlTUEdlcWpfaHRLdw (For some reason GoogleDocs is playing up and won’t accept .qvw’s so I’ve had to .rar it.)
As always; I hope you can find a use for it.
All the best,
