You can also use this (soon to be obsolete) method of merging all the numbers into the same list, and then splitting them using shift components. This way you avoid setting multiple graphs to the same values. The interval2 component at the right is set to "shortest list". The expression component has "x*x". You could also substitute this with a length component connected to one of the divide interval component. http://grasshopper3d.googlegroups.com/web/unevendistributeinterval2.jpg
