KxHistogram

The KxHistogram is a Sun MTPScan object composed of Motif widgets. A KxHistogram 
graphically depicts a changing datapoint value with a Scale instead of a 
KxValue. Note that the line inside the ScaleSlider represents the value, not the
top or bottom of the slider itself. A KxLabel below the Scale identifies what 
the KxHistogram represents, and the two KxLabels to depict the minimum (bottom)
and maximum (top) values for the Scale. 

If the value of a KxHistogram goes beyond the maximum or below the minimum, two 
things can happen. First, if a KxHistogram is set to auto-config, a boundary 
adjusts to accommodate a breaching value. Otherwise, the Scale remains pegged 
and the accompanying boundary KxLabel changes color (reverse for monochrome) to 
let you know that the actual value is (literally) off the Scale.

Use the PreferencesDialog to set the upper and lower boundaries for a given
KxHistogram. The Summary Screen's PreferencesDialog operates only on that 
Screen's objects. Likewise, an Overview Screen's PreferencesDialog works only
on the objects in Screens for a particular Sun MTP system. The PreferencesDialog 
also provides a toggle for automatic configuration, or auto-config, of each
KxHistogram. When auto-config is activated, the actual value can stretch the 
boundaries. Note that the range allowed for values in the PreferencesDialog are 
also configurable. Refer to the help on the Scale widget to learn how to set 
these values.
