What about comparing stocks metrics in one chart?

The comparison feature is really powerful. But an even more powerful way to see the differences is to show the comparative data in one chart. I.E. Compare P/S or ROIC for 1 to 5 different companies in one chart? Side by side is great (and shouldn't be taken away) but 5 different lines on top of each other might be even more effective to compare differences. I'm not suggesting taking away the side by side comparison, I'm suggesting adding another way to look at the data.
