Parallel Coordinates and Scatter without numeric attributes

former_member259476 — Thu, 28 Nov 2013 10:25:46 GMT

Hello community,

does anybody know a way to plot a Parallel Coordinates Chart and a (2D or 3D) Scatter Chart using non numeric attributes in PA?

I'm thinking about some visualizations like e.g. xdat is able to plot with only char-like attributes as input data.

Thanks and greetings,

Patrick

Hi Patrick,

Parallel coordinates and Scatter chart can not be drawn with non-numeric attributes in PA.

PA uses non-numeric attibutes only for coloring the Scatter and Parallel chart.

Regards,

Arti

Hi Patrick,

Can you share an example of such a chart?

Hi Patrick,

Thanks for the examples. The heatmap in the Prepare tab might fit the 2d scatter chart?

For the parallel coordinates chart I was thinking R might have something that could be used in a custom component. I could find a number of implementations for numerical values but none for texts I am afraid.

Hi Andreas,

the Heatmap seems to be a good approach for my use case.

Thanks a lot.

Hello Patrick,

Today I came across an R library that does the parallel coordinates chart on non-numeric attributes.

ggparallel

CRAN - Package ggparallel

Here is that chart in action

A Herath - Google+ - Story of Titanic -- Hammock Plotrequire(ggparallel)…

Are you comfortable writing your own add-on for SAP PA (Custom R Component)?

Greetings

Hi Andreas,

thank you for your help.

Our latest decision is to use UI5 and d3js to visualize the parallel coordinates chart.

Sample: US Presidents
