Feature request: customisable graphs

[VardenTheOne]

Select graphs to draw by name. Group it. ((Name, data_name, data_name), (Name, data_name, data_name), (Name, data_name, data_name))

Something like (("Attitude", "atttitude[0], "attitude[1]"), ("RC Input", "RC Command [roll]", "RC Command [pitch]")) In this case we will have two graphs (Attitude and RC Input). On first one w will have two lines ('atttitude[0]' and 'attitude[1]'), on second one two lines too (RC Command [roll], RC Command [pitch])

With such option we can draw any kind of graph we need for any king of aircraft
