Enumeration Type Documentation

◆ EAxisCompatibility

Enumerator
kIdentical 

Source and target axes are identical.

kContains 

The source is a subset of bins of the target axis.

kSampling 

The bins of the source axis have finer granularity, but the bin borders are compatible.

Example: source: 0., 1., 2., 3., 4., 5., 6.; target: 0., 2., 5., 6. Note that this is not a symmetrical property: only one of CanMerge(source, target), CanMap(target, source) can return kContains.

kIncompatible 

The source axis and target axis have different binning.

Example: source: 0., 1., 2., 3., 4., target: 0., 0.1, 0.2, 0.3, 0.4

Initialize a RColor from a string value.

Colors can be specified as RGBA (red green blue alpha) or RRGGBBAA: fa7f ffa07bff # hash introduces a comment! For all predefined colors in RColor, colors can be specified as name without leading 'k', e.g. red for RColor::kRed. Prints an error and returns RColor::kBlack if the attribute string cannot be parsed or if the attribute has no entry in fAttrs.

Parameters
name- the attribute name (for diagnostic purposes).
strval- the attribute value as a string.
