By default, the HistogramHeight property is 0. Use the HistogramVisible property to show or hide the histogram. The control allows to show workload and capacity by a histogram that automatically adapts to your current planning situation. The histogram may show the overloads 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 HistogramBackColor property to specify the histogram's background color. Use the HistogramPattern and HistogramColor property to define the shape, the pattern, the color or the skinning object to be used in defining your histogram for specifies type of bar. Use the OnResizeControl property on exDisableHistogram to prevent resizing the histogram at runtime. The HistogramBoundsChanged event notifies your application when the location and the size of the chart's histogram is changed, so you can use it to add your legend for the histogram in a panel component.
