pub struct SegmentedCoord<D: DiscreteRanged>(_);
Expand description
A SegmentedCoord
is a decorator on any discrete coordinate specification.
This decorator will convert the discrete coordiante in two ways:
- Add an extra dummy element after all the values in origianl discrete coordinate
- Logically each value
v
from original coordinate system is mapped into an segment[v, v+1)
wherev+1
denotes the sucessor of thev
- Introduce two types of values
SegmentValue::Exact(value)
which denotes the left end of value’s segment andSegmentValue::CenterOf(value)
which refers the center of the segment. This is used in histogram types, which uses a discrete coordinate as the buckets. The segmented coord always emitsCenterOf(value)
key points, thus it allows all the label and tick marks of the coordinate rendered in the middle of each segment. The coresponding trait IntoSegmentedCoord is used to apply this decorator to coordinates.
