By default, the HistogramCumulativeOriginalColorBars property is -1 ( True ). If the  HistogramCumulativeOriginalColorBars property is 0 (False), the bars that generate the cumulative histogram shows with a different color being specified by the HistogramCumulativeColor property. The HistogramCumulativeShowLegend property specifies the index of the column to show the legend for the items being displayed in the cumulative histogram. You can specify a non-existing column so the legend will not be shown in the left part of the histogram. Use the ItemBar(exBarColor) property to specify a different color for a specified bar. If the HistogramCumulativeOriginalColorBars property is 0 only bars that has the ItemBar(exBarColor) on 0 show with a different cumulative color. The ItemBar(exBarHistLegend) property specifies the description to show within the histogram's legend for the bar in the control's histogram (exKeepOriginalColor only).

If the HistogramCumulativeOriginalColorBars property is:

• -1, exShowCumulativeColor ( default ), the bars in the same item are represented in the histogram with a cumulative color. The color of the bar in the chart is not changed.
• 0, exChangeColor, the bars and their reflections in the histogram use a cumulative color to be shown. The color of the bar in the chart is changed accordingly to the cumulative color.
• 1, exKeepOriginalColor, the bars keeps their original color in the chart as in the histogram. The color of the bar in the chart is not changed. The ItemBar(exBarColor) property indicates the bar's color in histogram-representation as well. The ItemBar( exBarHistLegend) property specifies the description to show within the histogram's legend for the bar in the control's histogram ( exKeepOriginalColor only).

The following screen shots shows the histogram using different values for HistogramCumulativeOriginalColorBars property:

Original Layout	Histogram Representation, if the HistogramCumulativeOriginalColorBars is
This is the original layout, so no items are selected, and the effort for the bar in the "Item 1" is 2, and all bars has the same color.	-1 ( True ), by default is: The bars in the same item are represented in the histogram with a cumulative color. The color of the bar in the chart is not changed.
	0 (False) is: The bars and their reflections in the histogram use a cumulative color to be shown. The color of the bar in the chart is changed accordingly to the cumulative color.
This is the original layout, so no items are selected, and the effort for the bar in the "Item 1" is 2, and the item "Item 3" contains a red bar	1 ( exKeepOriginalColor ), is: The bars keeps their original color in the chart as in the histogram. The color of the bar in the chart is not changed. The ItemBar(exBarColor) property indicates the local bar's color. This option may be available for newer versions only.

The following screen shot shows the cumulative histogram for HistogramCumulativeColors = 8, HistogramCumulativeOriginalColorBars = 0 (False). In this case the A1, A2, A3, A4 and A5 bars are shown in the chart using a different color as specified by the cumulative histogram.

The following screen shot shows the cumulative histogram for HistogramCumulativeColors = 8, HistogramCumulativeOriginalColorBars = -1 (True). In this case the A1, A2, A3, A4 and A5 bars shows in the chart with the color to show the cumulative histogram.
