Caption: Figure 26.

Analogous to Figure 18 but for the metallicity instead of the age. VCC 1910 is not in the plot range due to its (likely wrong) supersolar metallicity. Due to the anticorrelation of age and metallicity (Figure 5) of our dEs, the positive correlation of the IMF parameter and the metallicity is a corollary of the IMF and age relation.
