Line2D(xdata, ydata[, linewidth, linestyle, ...]) A line - the line can have both a solid linestyle connecting all the vertices, and a marker at each vertex.
VertexSelector(line) Manage the callbacks to maintain a list of selected vertices for Line2D.


segment_hits(cx, cy, x, y, radius) Return the indices of the segments in the polyline with coordinates (cx, cy) that are within a distance radius of the point (x, y).
