Antonio,
The solution count chart on the convergence lines page shows the number of Pareto optimal solutions (blue) and the size of the current population (red). The pink band in the objective charts shows the range (min-max) of objective function values found in the optimal solutions, with the centre line marking the mean value. These charts are used to estimate convergence of the optimisation process. You can consider the process is converged if all the lines remain flat for a number of generations.
Depending on your problem, convergence may take a long time, though. The attached screenshots show that, for even a simple problem like the pre-calc example, full convergence is still difficult to achieve. After 200 generations the number of optimal solutions are still rising in this case.
