SymSpline

Property	Default	Meaning
f	—	Parametric function returning a numeric coordinate record, [x,y], or null
fx / fy	—	Coordinate functions or constants
xlim / ylim / tlim	[0, 1]	Sampling ranges when corresponding arrays are absent
xvals / yvals / tvals	—	Explicit coordinate or parameter arrays
samples	101	Number of generated samples
space	Automatic	Use ambient data coordinates or local geometry
tension	1	Catmull–Rom tangent strength; 0 makes straight segments
closed	false	Close each finite run

Use the sampling options described by SymLine and draw with Spline. Null/nonfinite samples split paths or omit markers. Use fy for y=f(x), fx for x=f(y), or f(t) for parametric points. Limits here control sampling; enclosing Graph/Plot limits control the view. Named records such as {theta, r} retain every dimension until the enclosing Graph projects them. Any nonfinite dimension creates a gap. fx, fy, xvals, and yvals retain their Cartesian meanings.

All Spline styling options are available. Construction stores immutable sampled data; resizing never executes callbacks. Spline interpolation can overshoot its data points.
