Member Function Documentation

QwtLinearColorMap * TwoDViewer::cmap	(	const int	mapId,
		bool	log
	)		const

private

retrieve a color id

the colormap needs be created on the heap and a pointer is then passed to the functions who will take over ownership and destroy the allocated space.

In case the mapId is unknown a standart black & white map is returned

Returns: pointer to the requested colormap

Parameters

mapId	the key of the requested color id
log	if true a log scale color map will be returned

Definition at line 361 of file two_d_viewer.cpp.

References map.

QStringList TwoDViewer::cmaps ( ) const

private

return the list of possible colormaps

Returns: list with possible colormap ids

QList< Data * > TwoDViewer::data ( )

virtual

set the data to display

Returns: list of data that is viewed by this viewer

void TwoDViewer::dataChanged ( )

virtual

update the plot

check if the zoomer is still valid and replot the plot

check if the data has really been updated, when it should original data

if the data is original, save the original histogram

reset flag

check if the user wants to convert cheetah layout to lab frame

create lookup table from the geom file if its not created yet

  check if the data is different (the bounding box changed) in which case we
  reinitialize the zoomer
  @note the below will be done when zooming into the initial bounding rect

_plot->setAxisScale(QwtPlot::yLeft,_data->boundingRect().top(),_data->boundingRect().bottom());

_plot->setAxisScale(QwtPlot::xBottom,_data->boundingRect().left(),_data->boundingRect().right());

void TwoDViewer::replot ( )

privateslot

replot the data

Note: we need to new the color bar for both the axis widget and the spectrogram as they take over possesion of the colorbar and delete them when they think appropriate.

get the data from the spectrogram and get the min and max z-values to be displayed

get the colormap to be used

set the colormap and min / max z-value

display the axis titles if requested

replot the plot

save the current settings
