Polar-Vector-ThetaRAM
Select X(θ)Y(r)YY columns to create vector plot (or quiver plot) in polar coordinate. 2nd Y represents angle, 3rd Y represents magnitude.
Select Plot > Specialized: Polar Vector θRAM
PolarVectorAM.otpu (All above are installed to the Origin program folder).
This is a XYAM vector in the polar coordinate, the θRAM columns contain the angle and radial coordinates of start points, the offset angle and magnitude of the vectors.
You can go to the Vector tab of Plot Details to customize the vectors.
