my plan is to create a map that shows the top 50 (by amount of passengers) international flights departing the United States (e.g. New York -> London, Honolulu -> Tokyo...). I want to use the plugin FlowMapper for QGIS to display those flights and have the width of the flows correspond with the amount of passengers. I have read the tutorial and had a look at the examples given (all in the download file of FlowMapper). The problem is, in those examples FlowMapper is only used for back and forth flows.
Thus, the data matrix in the examples looks like this, each row and column have the same:
But I want to use one way flows, so row and column have different geographical locations, like this:
So my question is, how does the flow matrix- and coordinates-file have to look like in order to be correctly displayed by the FlowMapper plugin?
This is my complete speadsheet that I wanna use as basis for my map: http://www.sendspace.com/file/ckaejd
