By cumulating the frequencies of the values or by adding up the probability function of the histogram you obtain the cumulative line (stepped graph) of the empirical values or the theoretical distribution function G(x). The ordinate (y-axis) has a linear scale. Hence each value has the same weight. This type of graphic helps you to evaluate the agreement between the cumulative function and the actual values and to evaluate the evaluation of the assumed distribution model. In case of a good agreement between the cumulative line and the stepped graph, the assumed distribution model is confirmed. The function approximates 0% or 100% asymptotically on the margins. The values of G(x) (e.g. fractions non-conforming) cannot be estimated or only approximately so in these regions.
