Detailed Description

The base class for drawing data points on the plot

Member Function Documentation

clip()

std::vector< Triangle > PlotGeometry::clip ( const std::vector< Triangle > &  ts ) const

protected

Take a list of polygon faces and crop them so that nothing extends outside of the charting space. Triangles completely outside the region are dropped while triangles partially within the region are converted into a group of polygons completely inside the bounds.

dataChanged

void PlotGeometry::dataChanged ( )

signal

The signal that is thrown when the data points have changed position in chart space

faces_()

std::vector< Triangle > PlotGeometry::faces_ ( std::vector< Vec3< float > >  points ) const

protectedvirtual

An array of polygon faces that would plot the given data points. The points should be in chart space (not data space).

updateData()

void PlotGeometry::updateData ( )

protected

Present the latest geometry to the renderer

Member Data Documentation

thickness_

double PlotGeometry::thickness_ = 0.01

protected

The size of the plotting geometry

xAxis_

Axis* PlotGeometry::xAxis_

protected

The axes along which the data are plotted

xs_

QList<double> PlotGeometry::xs_

protected

The coordinates of the data point along this axis

yAxis_

Axis * PlotGeometry::yAxis_

protected

The axes along which the data are plotted

ys_

QList<double> PlotGeometry::ys_

protected

The coordinates of the data point along this axis

Property Documentation

thickness

double PlotGeometry::thickness

The width of the data point drawing

xAxis

Axis * PlotGeometry::xAxis

The X axis that the data is plotted against

xs

QList<double> PlotGeometry::xs

The X coordinates of the data points in data space

yAxis

Axis * PlotGeometry::yAxis

The Y axis that the data is plotted against

ys

QList<double> PlotGeometry::ys

The Y coordinates of the data points in data space
