pslegend specfile column-wise
(using GMT 6.0.0_r19295 on mac).
I have notice that when preparing a specfile for use with pslegend in a two- or more-column layout, the plotting information (symbols and labels) has to be provided in a row-wise manner, i.e., I provide a symbol and label for the first row of the legend, across all of the columns, then the second row, and so forth.
I have found that generally I organize my legend information in columns rather than rows, e.g., with a column header and then legend items below. Having to specify the material row-wise makes the specfile hard to construct and is counterintuitive when reading it. As an example, consider the attached plotting script, specfile, and PDF output.
What I would like to do is provide a single column's worth of items to plot, and then a "column break" to advance to the top of the next column. Is anyone aware of a way to make pslegend interpret a specfile in this manner?
Many thanks in advance,
