The edge frequency polygon.
A piecewise linear competitor to the frequency polygon, the edge frequency polygon, is proposed: instead of joining histogram ordinates at midpoints of bins by straight lines, one connects values at bin edges by straight lines, those values being averages of contiguous histogram ordinates. The
new proposal is as simple and interpretable as the ordinary frequency polygon while holding theoretical and practical advantages.
