Detailed Description

Class for displaying data within a table as a xy image.

Intended use:

Internal or

Intended use:

Internal

Prerequisite

Etymology

"TblAsXYDD" is a implementation of a ActiveCaching2dDD which provides for the display of data held within a table to be displayed as a xy image in an environment where individual depictions of the data are automatically cached.

Synopsis

This class adds to the interface defined in DisplayData . It adds the capability to display data from a Table column as a xy image. It is assumed that the Y axis is defined to be either the row number of the table column being displayed or the scalar value from the same row number in a different table column (e.g. plotting intensity as a function of frequency against row number or time determined from a different column of the table). The X axis is assumed to be the data in a scalar table column.

Example

A TblAsXYDD object could be construed and used as follows:

TblAsXYDD *tardd1 = 0;
tardd1 = new TblAsXYDD("tablename");
Colormap cmap1("Hot Metal 2");
tardd1->setColormap(&cmap1, 1.0);
wcHolder->addDisplayData((DisplayData *)tardd1);

Motivation

To allow the display of data from a table as a xy image.

Template Type Argument Requirements (T)

To Do

make sure complex data are handled correctly
make sure table column units can be determined properly
make sure a scalar table column can be used for y axis
extend to n-dimensional arrays in table column
when constructed with *table we need to keep table from being deleted
handle movie axis once ActiveCachingNDim exists
implement showValue()
be able to derive xy plot data from columns with arrays
choose whether to draw points, lines or both
