set boxfrom <value>
The boxfrom setting alters PyXPlot’s behaviour when plotting bar charts. It changes the horizontal line (vertical point; -axis value) from which the boxes of bar charts appear to emanate. The default value is zero (i.e. boxes extend from the line of the
-axis). An example of its syntax would be:
set boxfrom 2
which would make the boxes of a barchart emanate vertically from the line .
