Hello all
I'm trying to create a directional spectrum in a 3D Polar system (see attached file). Circles are frequency intervals and Z-values are energy values. I want to create the right-hand figure in the attached file.
I appreciate any help you can provide. |

See the attached project.
1. Convert the matrix to xyz data in a worksheet: Go to menu Matrix->Convert to Worksheet... Set Method to XYZ Columns and click OK.
2. Transfer radius, theta data to X, Y data: Add two columns col(D) and col(E), set its values to A*cos(B), A*sin(B).
3. Add col(F) and copy data from col(C) to col(F).
4. Make 3D surface plot using column D, E, F.

Hi James;
Attached you can find the MATRIX of my data in .opju format.
First column (in Show X/Y Mode): Angles, between 0 and 356(~360) degrees.
First row (in Show X/Y Mode): Frequencies, between 0.02 and 0.91 Hz as circle scales.
Z (matrix) values are energy values.
Thank You.https://my.originlab.com/ftp/forum_and_kbase/Images/Export-Forum.opju |
