override

Destructor.

Member Function Documentation

GetBins()

int QmitkHistogramVisualizationWidget::GetBins

(

)

Returns the current number of histogram bins configured in the spin box.

Returns

The number of bins.

RequestHistogramUpdate

void QmitkHistogramVisualizationWidget::RequestHistogramUpdate ( unsigned int  nBins )

signal

Emitted when the user changes the number of bins.

Listeners (e.g., a statistics calculator) should connect to this signal and recalculate histogram data with the updated bin count.

Parameters

[in]

nBins

The new number of bins requested by the user.

Reset()

void QmitkHistogramVisualizationWidget::Reset

(

)

Clears all histogram data and disables all GUI elements.

ResetDefault()

void QmitkHistogramVisualizationWidget::ResetDefault

(

)

Resets all controls to their default settings.

Enables the default number of bins checkbox, sets bins to 100, and disables the subchart.

SetHistogram()

void QmitkHistogramVisualizationWidget::SetHistogram	(	itk::Statistics::Histogram< double >::ConstPointer	histogram,
		const std::string &	dataLabel
	)

Displays a histogram in the chart and enables the GUI controls.

If a histogram with the given label already exists, it is updated. Otherwise, a new histogram series is added to the chart.

Parameters

[in]	histogram	The ITK histogram to display. If nullptr, the call is ignored.
[in]	dataLabel	A unique label identifying this histogram series.

SetTheme()

void QmitkHistogramVisualizationWidget::SetTheme

(

QmitkChartWidget::ColorTheme

style

)

Sets the color theme for the chart widget.

Parameters

[in]
