Detailed Description

A 2D-plotting widget.

Graphs are managed by a MultiLayer, where they are sometimes referred to as "graphs" and sometimes as "layers". Other parts of the code also call them "plots", regardless of the fact that there's also a class Plot. Within the user interface, they are quite consistently called "layers".

Each graph owns a Plot called #d_plot, which handles parts of the curve, axis and marker management (similarly to QwtPlot), as well as the pickers d_zoomer (a QwtPlotZoomer), titlePicker (a TitlePicker), scalePicker (a ScalePicker) and cp (a CanvasPicker), which handle various parts of the user interaction.

Graph contains support for various curve types (see CurveType), some of them relying on Qtiplot-specific QwtPlotCurve subclasses for parts of the functionality.

Note that some of Graph's methods are implemented in analysis.cpp.

Future Plans

Merge with Plot and CanvasPicker. Think about merging in TitlePicker and ScalePicker. On the other hand, things like range selection, peak selection or (re)moving data points could be split out into tool classes like QwtPlotZoomer or SelectionMoveResizer.

What definitely should be split out are plot types like histograms and pie charts (TODO: which others?). We need a generic framework for this in any case so that new plot types can be implemented in plugins, and Graph could do with a little diet. Especially after merging in Plot and CanvasPicker. [ Framework needs to support plug-ins; assigned to ion ]
