mapValues

the value or the colour of every measurement or grain, and whether it is a value a colour map turns into colours: what a map plot draws, before it is drawn

Syntax

rgb, scalar = mapValues(ebsd, 'phase')

v, scalar = mapValues(ebsd, 'mad')

rgb, scalar = mapValues(ebsd, None, ipfDirection=xvector) # inverse pole figure colours along x

rgb, scalar = mapValues(ebsd['Forsterite'], key)

rgb, scalar = mapValues(ebsd, 'mad', at=ind)

Description

The colouring asked for is one of:

• None or ‘phase’: the colours of the phases.
• ‘orientation’, or an ipfDirection alone: every phase through the inverse pole figure key of its own frame.
• an orientation per element: through the inverse pole figure key of its phase.
• an orientationColorKey: the phases of its frame through the key, the others by their own inverse pole figure key for an ipfColorKey, else white.
• the name of a property, or of a value per element the map or the grains compute (area, perimeter, aspectRatio, …): values.
• a value or an RGB colour per element.
• one colour, a name or an RGB triple, for all; or faceColor alone.

A site without an orientation is white, a not indexed phase too unless its frame has a colour of its own.

at= colours only the elements a picture shows, for a large map. Values are returned for all elements regardless, since the colour range belongs to the whole map; colours are returned one per entry of at.
