BestCost = [rand(1,10); rand(1,10)];
semilogy(BestCost.','linewidth',2)
xlabel('Iteration');
ylabel('Best Cost');
legend('normal','stop and watch')

Don't need explicit x nor to plot each individually -- the one argument as a 2-column array uses the builtin interpretation by plot and friends to treat columns as separate variables; it rotates through the default colormap automagically, too.

In the plotting functions, once you have start the first name/value pair, everything else on the line must be name/value pairs.
The plotting functions do not permit adding name/value pairs for each distinct set of data: the name/value pairs must go after all data specifications, and the name/value pairs will apply to all sets of data in the same call.
