Folks, I forgot to mention on Tuesday's teleconference, a useful feature in Performance mode. If you click Performance, above the graphs is a summary with a far left column containing checkboxes. Those checkboxes allow you to ''cherry pick'' which rows to plot in the below graphs. So you can check/uncheck them and then click the ''cherry'' button at the foot of the table to prune out line plots. Test it out here:
