Design a way to represent numeric data associated with an interval

[kaufmanno]

I propose an approach based on categories because:

• such an approach has already been implemented for lithologies
• such an approach could, given certain implementation details, allow from a representation with striplog of these categories on 1D borehole graphs
• "continuous" colorscales are more difficult to use in a 3D viewer where lighting and occlusion from semi-transparent objects interfere with the actual rendered colors

[kaufmanno]

For the implementation, we see two possibilities (non excluding): a) create a new component for each category of the attribute (ex: Benzene over "VI") and associate a component from this set to an interval using a function that translates the values stored into the extra data of the associated table between this interval and one (or several) given component(s) (ex 'Benzene') + create a lexicon and a legend to display this categories; b) create a function that transforms a numerical value stored in the extra data in the association table between an interval and a component into a way to represention

Extra comments:

• Solution a) inserts new components in the db and requires to build a lexicon and a legend it has to be implemented before a display and is rather 'static'
• Solution b) seems more dynamic as it takes place at the display stage and doesn't impact the db (but more processing might be needed on the fly)

I think that the best strategy is to go for solution a first and come back to solution b later on if needed...
