set boxwidth <width>
The ‘boxwidth’ setting alters PyXPlot’s behaviour when plotting bar charts. It sets the default width of the boxes used, in graph -axis units. If the specified width is negative then, as happens by default, the boxes have automatically selected widths, such that the interfaces between them occur at the horizontal midpoints between their specified
-positions. For example:
set boxwidth 2
would set all boxes to be two units wide.
set boxwidth -2
would set all of the bars to have differing widths, centred upon their specified -positions, such that their interfaces occur at the horizontal midpoints between them.
