flowmap arrow

[sgavathe]

Hello,

Anyone know how to draw the flowmap directional arrow on both side of the line instead of half arrow ?

Hi Shailesh,

You just need to include the reverse direction flow into your data. So if you only have some count for the pair of origin A and dest B, you need to add another row into your flows dataset with the origin B, dest C and some non-zero count.

Does this answer your question?

Thank you Ilya.

I was struggling to see how the positions are laid out. Does each of these mean vertices ? Sorry, not too familiar with the positions and normals.

0, 0, 0, 0, 1, 0, 1, 0, 0,

This is something very custom. Each three numbers are for one vertex.

[ilyabo]

The three values for one vertex have these meanings respectively to displace the vertex:

source_target_mix, perpendicular_offset_in_thickness_units, direction_of_travel_offset_in_thickness_units

[ilyabo]

source_target_mix means the displacement from the source towards the target

ahh got you Ilya.

Makes sense on how positions are done for vertex and how numbers representing for a shape. Thanks a lot.
