Data::Plot class reference
[Core module]


#include <Goptical/Data/Plot>

namespace Goptical {
namespace Data {
class Plot;

This class is a member of the Data namespace.



This class is used to describe a data plot. It contains a list of PlotData objects and describes some plot properties (title, range, ...).

Plots can be built from data sets or obtained directly from various analysis functions. They can be rendered on a Io::RendererViewport object with the draw function.


See also the full member list section for this class.
