Hi Ferreters, First of all, i would like to thank the Ferret developers and users, who made "Ferret" as a wonedrfull tool for climate community and Ferret Users Forum as an enjoyable place, providing with many challenging questions and quite helpfull answers. As a reward, this is what i got for you............color_vector.jnl There were many discussions about colorizing vector plots and the two options we have are (1) poly_vectors (written by Ned Cokelet and modified later by William Kessler) and (2) multiple overlays with /COLOR qualifier. While the vectors resulting (1) were bit bulky, compared to the default sharp vectors given by Ferret's VECTOR command, method (2) was bit tedious. The present GO file (color_vector) is a generalized form of method (2), based on a specified palette file (sounds cool??) and color/shading levels. However, according to present implementation, the coloring can be based only on the scalar magnitude of the vector field. But, there are options for almost all qualifiers to default vector command. For a quick look, please see the attached figure (color_vector_demo.gif). Attached tar.gz file does have two scripts, color_vector.jnl and color_vector_demo.jnl. To know more about capabilities and limitations of new GO file, please read the header part of color_vectors.jnl. For usage details and real world examples, please have trial with color_vector_demo.jnl. You must have thought that, if we can plot vectors based on a palette file, why can't we draw contours? Hold on ...... Hope you find this new GO tool usefull. Comments and suggestions are most welcome....
