Arguments

from	start node
to	end node
label_from	label to draw on the flow out of from
label_to	label to draw on the flow into to
pos_from	a decimal between 0 and 1 giving the position to start the flow out of from, where 0 = bottom and 1 = top
pos_to	a decimal between 0 and 1 giving the position to attach the flow to node to, where 0 = left and 1 = right
label_from_pos	a decimal between 0 and 1 giving the position along the flow out of from to draw label_from, where 0 = start and 1 = end
label_to_pos	a decimal between 0 and 1 giving the position along the flow into to to draw label_to, where 0 = start and 1 = end
label_from_gap	distance from the flow out of from at which to draw label_from default = 0.05
label_to_gap	distance from the flow into to at which to draw label_to default = 0.05
label_from_x	x co-ordinate of label_from position, overrides use of label_from_pos and / or label_from_gap
label_to_x	x co-ordinate of label_to position, overrides use of label_to_pos and / or label_to_gap
label_from_y	y co-ordinate of label_from position, overrides use of label_from_pos and / or label_from_gap
label_to_y	y co-ordinate of label_to position, overrides use of label_to_pos and / or label_to_gap
arr_width	width of arrow, defaults to same as flow()
name_from	internal argument used for informative error messages
name_to	internal argument used for informative error messages
...	additional formatting arguments to flow()

Value

returns the start and end points of the flow
