Detailed Description

Class for XY-type simple graph plots.

Implementation of Graph. Used in Frame type plots.

Constructor & Destructor Documentation

XYGraph() [1/2]

XYGraph::XYGraph

(

)

Default constructor for empty graph.

XYGraph() [2/2]

XYGraph::XYGraph	(	const std::vector< double > &	xdata,
		const std::vector< double > &	ydata
	)

Constructor for basic graph with datapoints xdata and ydata.

Internal copies of the data from xdata and ydata are made.

~XYGraph()

virtual XYGraph::~XYGraph ( )

inlinevirtual

Destructor.

Member Function Documentation

extend_histogram()

void XYGraph::extend_histogram

(

bool

extend

)

Extend histogram.

Set to true for histogram to be extended in x-direction to cover all of range.

get_bbox()

void XYGraph::get_bbox ( double  bbox[4] )

virtual

Get bounding box of graph.

Returns the bounding box of the graph in array bbox in order xmin, ymin, xmax, ymax.

Implements Graph.

plot()

void XYGraph::plot ( cairo_t *  cairo, const Coordmapper *  cm, const double  range[4]  )

virtual

Plot graph with cairo.

Plot the graph using cairo and coordinate mapper cm. The visible range of plot is given in array range in order xmin, ymin, xmax, ymax. The graph should be able to handle any range values. Also min > max.

Called by Frame during drawing.

Implements Graph.

plot_sample()

void XYGraph::plot_sample ( cairo_t *  cairo, double  x, double  y, double  width, double  height  )

virtual

Plot sample for legend.

Plot graph sample for legend at cairo coordinates (x,y).

Implements Graph.

set_color()

void XYGraph::set_color

(

const Vec3D &

color

)

Set graph color.

Defaults to red (1,0,0).

set_data()

void XYGraph::set_data	(	const std::vector< double > &	xdata,
		const std::vector< double > &	ydata
	)

Set new data arrays.

set_histogram()

void XYGraph::set_histogram

(

bool

histo

)

Set histogram style.

Set to true for histogram style plots.

set_line_style()

void XYGraph::set_line_style	(	line_style_e	linestyle,
		double	linewidth = 1.0
	)

Set line style.

Defaults to no lines drawn (XYGRAPH_LINE_DISABLE)

set_line_width()

void XYGraph::set_line_width

(

double

linewidth

)

Set line width.

Default to width 1.0.

set_point_style()

void XYGraph::set_point_style	(	point_style_e	pointstyle,
		bool	filled = true,
		double	scale = 1.0
	)

Set point style.

Defaults to filled XYGRAPH_POINT_CIRCLE with scale 3.0.
