Member Function Documentation

◆ clearStretch()

void Isis::HistogramWidget::clearStretch ( )

Clears the stretch curve from the plot.

Definition at line 130 of file HistogramWidget.cpp.

References p_stretchCurve.

◆ heightForWidth()

int Isis::HistogramWidget::heightForWidth ( int w) const

◆ setHistogram()

void Isis::HistogramWidget::setHistogram ( const Histogram & hist)

Creates a histogram curve from the given histogram and plots it.

Parameters
hist
