• exOverviewShowDateTimeScaleBottom(0x1800), specifies whether the overview's date-time scale is displayed on the bottom side of the overview. By default, the time-scale of the overview part is shown on the top of it, so you can use the exOverviewShowDateTimeScaleBottom flag with exOverviewShowDateTimeScale or exOverviewShowDateTimeScaleSplit to display the time-scale on the bottom side of the overview part of the control
• exOverviewShowMargins(0x2000), displays the limits of the overview bars. You can include the exOverviewShowMargins flag to display the margins/limits of all (project) / visible bars. In other words, the exOverviewShowMargins flag displays the minimal ItemBar(exBarStart) value, and the maximal ItemBar(exBarEnd) value
• exOverviewShowSelMargins(0x4000), displays the selection limits (first/last visible date in the chart)
• exOverviewSplitter(0x10000), specifies whether the overview's horizontal splitter is visible or hidden(makes the control's overview resizable or fixed)
