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 = left and 1 = right
pos_to	a decimal between 0 and 1 giving the position to attach the flow to node `to`, where 0 = bottom and 1 = top
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
