Detailed Description

Encapsulates a point in the plot.

A KPlotPoint consists of X and Y coordinates (in Data units), an optional label string, and an optional bar-width, The bar-width is only used for plots of type KPlotObject::Bars, and it allows the width of each bar to be set manually. If bar-widths are omitted, then the widths will be set automatically, based on the halfway-mark between adjacent points.

Constructor & Destructor Documentation

KPlotPoint::KPlotPoint ( )
explicit

Default constructor.

Definition at line 28 of file kplotpoint.cpp.

KPlotPoint::KPlotPoint ( double  x,
double  y,
const QString label = QString(),
double  width = 0.0 
)

Constructor.

Sets the KPlotPoint according to the given arguments

Parameters
xthe X-position for the point, in Data units
ythe Y-position for the point, in Data units
labelthe label string for the point. If the string is defined, the point will be labeled in the plot.
widththe bar width to use for this point (only used for plots of type KPlotObject::Bars)
