enum Interpolate
The line interpolation method to use for line and area marks. One of the following:
"linear"
: piecewise linear segments, as in a polyline."linear-closed"
: close the linear segments to form a polygon."step"
: alternate between horizontal and vertical segments, as in a step function."step-before"
: alternate between vertical and horizontal segments, as in a step function."step-after"
: alternate between horizontal and vertical segments, as in a step function."basis"
: a B-spline, with control point duplication on the ends."basis-open"
: an open B-spline; may not intersect the start or end."basis-closed"
: a closed B-spline, as in a loop."cardinal"
: a Cardinal spline, with control point duplication on the ends."cardinal-open"
: an open Cardinal spline; may not intersect the start or end, but will intersect other control points."cardinal-closed"
: a closed Cardinal spline, as in a loop."bundle"
: equivalent to basis, except the tension parameter is used to straighten the spline."monotone"
: cubic interpolation that preserves monotonicity in y.
The line interpolation method for the error band. One of the following:
"linear"
: piecewise linear segments, as in a polyline."linear-closed"
: close the linear segments to form a polygon."step"
: a piecewise constant function (a step function) consisting of alternating horizontal and vertical lines. The y-value changes at the midpoint of each pair of adjacent x-values."step-before"
: a piecewise constant function (a step function) consisting of alternating horizontal and vertical lines. The y-value changes before the x-value."step-after"
: a piecewise constant function (a step function) consisting of alternating horizontal and vertical lines. The y-value changes after the x-value."basis"
: a B-spline, with control point duplication on the ends."basis-open"
: an open B-spline; may not intersect the start or end."basis-closed"
: a closed B-spline, as in a loop."cardinal"
: a Cardinal spline, with control point duplication on the ends."cardinal-open"
: an open Cardinal spline; may not intersect the start or end, but will intersect other control points."cardinal-closed"
: a closed Cardinal spline, as in a loop."bundle"
: equivalent to basis, except the tension parameter is used to straighten the spline."monotone"
: cubic interpolation that preserves monotonicity in y.
