Function CopyValues

plot/data.go:98–114

CopyValues returns a Values that is a copy of the values from a Valuer, or an error if there are no values, or if one of the copied values is a Infinity. NaN values are skipped in the copying process.

(vs Valuer)

// the copied values is a Infinity.
// NaN values are skipped in the copying process.

	cpy := make(Values, 0, vs.Len())
	for i := 0; i < vs.Len(); i++ {
		v := vs.Value(i)
		if math32.IsNaN(v) {
			continue
		}
		if err := CheckFloats(v); err != nil {
			return nil, err
		}
		cpy = append(cpy, v)
