Scatter chart

A scatter chart draws a single point for each point of data in a series without connecting them.

Scatter chart features

An important distinction between a scatter series and a line series is that the scatter series doesn't require sorting because the mouse tracker for the tooltip is activated on each single marker. A line can be drawn between the markers by setting the lineWidth option to something higher than 0.

For an overview of the scatter chart options see the API reference.

Jittering

Jittering can be very useful for some charts using scatter points. Sometimes the data displayed are one dimensional, and would appear as a single line on the chart. Jitter helps separate the datapoints from each other making the properties of the series more apparent.

See an example of Jittering.

Clustering

Scatter charts are especially useful for visualizing clustered data. Adding functions to cluster data into points combined with individual coloring of points in a series makes cluster visualization trivial.

See an example of Clustering.

3D scatter charts

In 3D charts, the scatter points also have a Z dimension. This is handled by a separate series type, scatter3D.
