With the Full version, you have no limits:

unlimited number of components

unlimited number of nodes

unlimited number of curves 

unlimited number of datapoints in each analysis

unlimited number of lines in each analysis


Also the full version has all the color modes of the other versions, and additionally has the night-mode. The night mode is useful if you are working long hours in front of the screen.
