I downloaded the Flowmapper plugin for Qgis and I can't seem to find any information on how it is supposed to work...

Also the text seems to cut-off and not fully showing for the input fields so I'm not quite sure what the fields should be anyway...

Here is an example of what I mean: enter image description here

I tried to select a file storing my node coordinates but am not allowed to (greyed-out) pick files that are .csv, .dbf, .shp or seemingly any of the filetypes on my computer... Which is why I started looking for some information on how to use the Flow Mapper plug-in, after finding nothing descriptive I thought it would be easier to ask someone who has maybe used it successfully before.

For reference I have a point file of centroids of polygons and I have a collection of lat long points which contain an attribute that should connect them to one of the above mentioned centroids. Maybe there is a better way to do this?

QGIS 1.8.0 on Mac

Thanks

And I did try expanding the window... The content doesn't shift with the window... –  Chewy Mar 28 '13 at 17:18

I am the developer of this plugin. Yet it is still experimental; but fully working. The plugin pack you have downloaded already includes a PDF TUTORIAL file. Please read it. Flow mapper plug-in is tested to be working under Windows. Thus, I cannot guarantee it to work under mac-os. It would probably have path problems.

You can only select txt files for input. First should store your node coordinates and second should store the interaction matrix between them. Then you can create node2node flow lines as shapefile.
