Fraction of galaxies with different values of the Bar Length attribute as a function of EFIGI morphological type for the 3106 EFIGI galaxies with Inclination-Elongation  ≤ 2. This graph shows that bars are frequent among all galaxy types except E and dE, and the strongest bars lie in early-type spirals. For clarity, the Poisson error bars in the fractions with Bar Length = 2 are not plotted; these are listed in Table 5 and are comparable to those for the other plotted attribute values.
