Numerical with Frequency

The Numerical with Frequency strategy allows visualizing triplets as coordinates (x, y) with an associated numeric frequency.

Intent​

It attempts to answer the following sensemaking task:

  • What is the relationship between three numeric variables?

Presentation metaphor​

Data, together with Numerical.

Context meta-model​

The context meta-model of Numerical with Frequency contains a single class, Target, with three numeric attributes: x, y, and freq.

Visualisation variants​

  • Bubble Chart displays coordinates as bubbles with a size proportional to the frequency freq.

Visualisation variant of Numerical with frequency.

Properties​

  • title : string [1..1]. Title of the visualisation.
  • X_label : string [0..1]. Label for the x axis.
  • Y_label : string [0..1]. Label for the y axis.
