Detailed Description

Definition at line 2823 of file qcustomplot.h.

Member Enumeration Documentation

Defines the ways the width of the bar can be specified. Thus it defines what the number passed to setWidth actually means.

See also
setWidthType, setWidth

Bar width is in absolute pixels.


Bar width is given by a fraction of the axis rect size.


Bar width is in key coordinates and thus scales with the key axis range.
