* \brief A graphical sink to display a histogram.

*
* \details
* This is a QT-based graphical sink the displays a histogram of
* the data.
*
* This histogram allows you to set and change at runtime the
* number of points to plot at once and the number of bins in the
* histogram. Both x and y-axis have their own auto-scaling
* behavior. By default, auto-scaling the y-axis is turned on and
* continuously updates the y-axis max value based on the
* currently plotted histogram.
*
* The x-axis auto-scaling function only updates once when
* clicked. This resets the x-axis to the current range of minimum
* and maximum values represented in the histogram. It resets any
* values currently displayed because the location and width of
* the bins may have changed.
*
* The histogram also has an accumulate function that simply
* accumulates the data between calls to work. When accumulate is
* activated, the y-axis autoscaling is turned on by default as
* the values will quickly grow in the this direction.
