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.
