	internally stores information about one data column. See JKQTPDatastore for more information. More...
class	JKQTPColumnBackInserter
	iterator, which allows to insert into a column of a JKQTPDatastore More...

class	JKQTPColumnIterator
	iterator over the data in the column of a JKQTPDatastore More...
class	JKQTPDatastore
	This class manages data columns (with entries of type double ), used by JKQTPlotter/JKQTBasePlotter to represent data for plots. More...
class	JKQTPDatastoreItem
	this represents one chunk of memory which can represent one or more columns of data for JKQTBasePlotter. See JKQTPDatastore for more information. More...
class	JKQTPDatastoreModel
	QAbstractTableModel descendent that allows to view data in a JKQTPDatastore. More...

Detailed Description

The classes in this group implement a data storage system for use with the main plotter class. Basically a table of data is generated as a set of logical columns that may be bound to different data sources (internal or external memory arrays. Later on it is simply possible to plot graphs using the column number and the not a link to the actual data array, as the link is stored in these classes.

Enumerator
SingleColumn	a 1D C-array of doubles. (default option)
MatrixColumn	a 1D C-array of doubles that represents a number of columns. The data is store column after column (=column-major).
MatrixRow	a 1D C-array of doubles that represents a number of rows (C standard representation of matrices). The data is stored row after row (=row-major).
