-\FIXME{explain how to read the graphs}
-
-each bar -> times for an algorithm
-recall the different times
-no bar -> not run or did not converge in allocated time
-
-repeated for the different platform sizes.
+Finally, on the graphs, the vertical bars show the measured times for each of
+the algorithms. These measured times are, from bottom to top, the average idle
+time, the average convergence date, and the maximum convergence date (see
+Section~\ref{sec.metrics}). The measurements are repeated for the different
+platform sizes. Some bars are missing, specially for large platforms. This is
+either because the algorithm did not reach the convergence state in the
+allocated time, or because we simply decided not to run it.
