Detailed Description

A data handler class.

DataHandler is a class that contains Constants defining how data read from _readers_ will be interpreted. It also contains a static data structure which contains curve data for plots currently on screen.

See also:: SimplePlot::setData(), DetailPlot::setData(), Plotting

Definition at line 40 of file datahandler.h.

Member Enumeration Documentation

enum DataHandler::Constants

Constants defining curve / line attributes.

Enumerator:

numberofLines	How many curves/lines to show on the screen at once.
secondsprLine	How many seconds of data does a curve/line contains.
secondsprDetailLine	How many seconds of data does a detailed curve/line contain.
standardSamplingRate	Standard sampling rate for this application.
