I am trying to plot vector following the poly_vector_demo; with increment/skip every nth-grid and filled by speed magnitude.
After some the steps, such as followings:
- go basemap
- go poly_vectors.jnl
- polygon/ov/noax/nolab/key plt_x_arrow,plt_y_arrow,speed
I still couldn't find the appropriate way to create what I need, the results is as attached figure (too crowded).
I wish there would be some suggestion regarding my issue.
I would be more eager and fully appreciate for any comments and suggestions, thank you very much.
