Detailed Description
Class for XY-type simple graph plots.
Implementation of Graph. Used in Frame type plots.
Constructor & Destructor Documentation
| XYGraph::XYGraph | ( | ) |
Default constructor for empty graph.
| 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.
| virtual XYGraph::~XYGraph | ( | ) | [inline, virtual] |
Destructor.
Member Function Documentation
| void XYGraph::extend_histogram | ( | bool | extend | ) |
Extend histogram.
Set to true for histogram to be extended in x-direction to cover all of range.
| virtual 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.
