Plotting boxes

Gnuplot's box style is similar to a bar chart, with each value plotted as a box extending up from the axis. You can have the boxes filled with patterns, solid colors, or leave them empty.

This style is commonly used either as a type of histogram (covered later in this chapter) or as a way to compare a set of disparate items. The following figure plots boxes using the fill pattern:
