Count of Graph items in viewport?

Post by VideoTrack » Tue Nov 06, 2018 10:06 am

I have a graph with a scroll bar to scroll through the contents of a bar series. The 'visible' contents of the bar series are much less than the total bar series count. How can I determine programmatically how many bar series items in the graph are 'visible' in the viewport of the series?

In other words, how many of each bar series the user can visibly see in the displayed window?

Hello,

You can use the series VisibleCount function to get the number of points currently visible.
