By default, the HistogramVisible property is False ( hidden ). The control allows showing workload and capacity by a histogram that automatically adapts to your current planning situation. The histogram may show the overloads, overallocations and subloads for visible bars, or for selected bars. Over-loads and Sub-loads can be shown in several ways using curves, patterns or colors in the same histogram. They are updated interactively, so as user moves or resizes a bar, the histogram is updated automatically. Use the HistogramHeight property to specify at runtime the height of the histogram. Use the HistogramBackColor property to specify the histogram's background color. 

Use the HistogramPattern, HistogramColor and HistogramType properties to define the shape, the pattern, the color or the skinning object, and the type of the graph, to be used in defining your histogram for specified type of bars. A bar is represented in the histogram only if HistogramPattern or HistogramColor property is set. If any of these are not set, the bar will not be represented in the histogram.

The following screen shot shows the exHistOverload histogram and how it is updated as soon the bars are moved or resized:

The following screen shot shows the exHistOverAllocation histogram and how it is updated as soon the bars are moved or resized:

Bellow you can view few screen shots of histograms being displayed in different ways, using different color, patterns, curves or EBN skin files:

Use the Background(exSplitBar) property to define the shape and the color for horizontal split bar, that may be used to resize the histogram at runtime.
