Display and manipulate a histogram of the data. When the histogram filter is active, not only will a histogram of the full data set be displayed, but some of the properties of it can be changed. The minimum and maximum data values in the histogram can be changed as needed. However, extreme care should be taken when manipulating these values as they will change the values used and displayed in later processing stages. If data values are excluded in the histogram filter, the changes may affect the values being used to manipulate the images through the window and level sliders.
