Legend Spacing and Margins

New parameters in theme() to customize the legend spacing and margins:

  • legend_box - arrangement of multiple legends ("horizontal" or "vertical");
  • legend_box_just - justification of each legend within the overall bounding box ("top", "bottom", "left", "right", "center");

  • legend_box_spacing - spacing between plotting area and legend box;

  • legend_margin - margin around each legend;

  • legend_spacing - spacing between legends, legend_spacing_x/legend_spacing_y - in the horizontal/vertical direction.
