Enumeration Type Documentation

EAxisCompatibility

enum class ROOT::Experimental::EAxisCompatibility

strong

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

FromAttributeString() [1/17]

ROOT::Experimental::RColor ROOT::Experimental::FromAttributeString	(	const std::string &	strval,

		RColor *
	)

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.
