Glyphs




Glyph are techniques which map data values to various geometric and color attributes of graphical primitives or symbols. One of the most widely recognised form of glyph is histograms where data values control the height of rectangular bars. The star glyph pattern, which creates for each point N rays emanating at equal angles from a point on the screen. The length of each ray is determined by the data value for that dimension. A polyline is then generated to encompass the rays, forming a blob shape.

This technique can be used to look for similar shapes and simple transitions between shapes. It is also fairly easy to spot anomalies.
