Scatter Plot
Try It
Description
This tool takes data and plots it as co-ordinates in 2D or 3D space. The graph can be rotated, panned, and zoomed. Data can be viewed along a particular axis by pressing the corresponding key, i.e. x, y, z. Rolling over a data node will display detailed co-ordinate information.
Currently this applet works primarily with the Principal Components Analysis tool, where each axis represents an eigenvector.
This tool uses the
processing library.
* This tool requires the
JRE (v1.4.2 and up) in order to work properly.
Pseudocode
- get the data provided by the Principal Components Analysis tool and process it to determine maximum values
- create nodes for each word using the data
- initialize the processing environment
- draw axes and nodes
- setup listeners for keyboard and mouse actions
Responsibility
This tool was programmed by Andrew MacDonald as part of the
TAPoR project.
