property Chart.MarkNowTransparent as Long
Specifies the percent of the transparency to display the object that marks the current time.

TypeDescription
Long A long expression that specifies the percent of transparency to show the vertical bar that indicates the current date-time in the control's chart. 0 means opaque, 50 means semi-transparent, and 100 means transparent.
By default, the MarkNowTransparent property is 0. The control's chart shows the position of the current date-time, only if the MarkNowColor property is not zero (0). The MarkNowTransparent property specifies the percent of transparency to show the vertical bar that indicates the current date-time. The MarkNowUnit property specifies the unit of time to count for. For instance, you can show the current date-time from current second, to next second, from minute to next minute, and so on. Use the MarkNowCount property to specify the number of units of date-time to count from. For instance, you can show the current date-time from 5 seconds to 5 seconds, and so on. The MarkNowWidth property specifies the width in pixels of the vertical bar that shows the current date-time. The MarkTodayColor property highlights the current day only. The control fires the DateTimeChanged event when the current date-time is changed.
