RESPITE: The CASA Toolkit Page: Documentation: Block Library Index:QFigure


QFigure

The QFigure block is used to display data. It may be used to display either sample or 1-D frame data. Sample data will produce a simple 2-D x-y graph. 1-D frame data will produce a 2-D grey-scale type image.

The initial size of the figures produced can be set using the WIDTH and HEIGHT parameters. The TITLE parameter can be used to give a name to the window in which the figure appears.

To produces figures the QFigure block requires that CTK has been compiled with Qt support. If the toolkit has been compiled without Qt support, or if the ACTIVE switch is set to false, then data will pass through the block with no effect.
