Citrin Bubble Charts

Bubble charts are like an X-Y scatter chart with values of a 3rd variable displayed using the size of the bubble marker or a color scale.

Citrin provides diverse bubble chart types, round and square bubble markers, and several options for scaling the size of bubble markers. The area or radius of bubble markers can be scaled proportional to the values of the bubble variable data range, using either a linear or a logarithmic scale.


Bubble Charts Displaying Values of a 4th Dimension

Standard bubble charts display three dimensions, X, Y, and bubble variable. Citrin allows displaying values of a 4rd variable on a bubble chart using a color-scale:

A Bubble Chart Representing Four Variables

Bubble Charts Displaying Values of Five Variables

Here, the values of the 3rd, 4th, and 5th variables are represented using the bubble size, a color-scale, and value labels, respectively.

For readability purposes, displaying a 5th dimension as value labels on a bubble chart is only suitable for very small data sets.

Standard Bubble Charts

In a standard bubble chart, Citrin allow values of the bubble variable to be displayed either by the size of bubble markers (see the left-hand side image below) or a color scale (see the right-hand side image below).
