Bubble charts
Simple bubble chart
Example of a simple bubble chart. A bubble chart is used to
visualize a data set with two to four dimensions. The first two dimensions are
visualized as coordinates, the third as color and the fourth as size. Bubble charts
can be considered a variation of the scatter plot, in which the data points are
replaced with bubbles. By default all bubble charts display tips when hovering over
bubbles.
Color by numbers
Example of a simple bubble chart, where the bubbles are colored in
proportion to a value using the colorAxis option. Depending on the
data, bubbles can have one or more colors. In this example we've set start and end
colors, color scale will be based on them. Minimum and maximum values are set
automatically. Both x-axes and y-axes are numeric in bubble charts unlike in other
charts, where axes are numeric and categorical.
Scatter charts
Simple scatter chart
Example of a simple scatter chart. A scatter chart is a
type of mathematical diagram using Cartesian
coordinates to display values for two variables for a set of data. The
data is displayed as a collection of points, each having the value of one variable
determining the position on the horizontal axis and the value of the other variable
determining the position on the vertical axis. When the user hovers over the points,
tooltips are displayed with more information.
Diff scatter chart
A diff chart is a chart designed to highlight the
differences between two charts with comparable data. By making the changes between
analogous values prominent, they can reveal variations between datasets. You create
a diff chart by calling the computeDiff method with two datasets to generate a third
dataset representing the diff, and then drawing that. Supports all scatter chart
options, as it jsut combines 2 charts into 1.
