Interactive dynamic graphics program for data visualization
XGobi is an interactive dynamic graphics program for data visualization
in the X Window System. It is especially designed for the exploration of
multivariate data. Its basic plot is a scatterplot, and these are some of
the tools available for scatterplot display and manipulation:
- Cycling rapidly through two-variable scatter plots.
- Three-dimensional rotation, including trackball control.
- Grand tour rotation: a smooth randomized sequence of two-dimensional
projections in order to explore a higher-dimensional point cloud.
- Brushing: the ability to change the color or plotting character of a
point or a group of points.
- Scaling: moving and reshaping the plot interactively.
- Identification: displaying an label next to a point in the plot window.
- Linking: Brushing, identification and touring are linked; that is,
actions in the window of one XGobi process are immediately reflected
in another XGobi window displaying the same data.
- Line editing: Any pair of points can be connected with a line segment.
- Transformation: A menu of data transformations is available.
- Postscript plotting: The contents of the plot windows can be written
out to postscript files for high-quality plotting.
