How External Data Plotting Works

How External Data plotting works

An "external data" file is generated (externally) by the user, by any means, that contains some or all of the following attributes:

• Arbitrary data values at three-dimensional coordinates in space
• Contour band values and colours
• Information about symbol size and labelling
• Lines used to demarcate regions

D3PLOT reads this file, supplying defaults for information that is not specified, and displays the results on top of the current image. This display can be turned on or off at will, and modified at any time.

External data is stored on a "per model" basis, so if you have multiple models data has to be read separately for each model and its visual attributes may also be controlled separately.
