bars count for displayed bars

[pjsmith]

Hi,

Without using OnRender to loop through the bars needed, is there any way, in onbarupdate, to see how many bars the user has on the screen?

Thanks.

Hello pjsmith,

Thank you for your post.

You can get the current count of the bars on screen by using ChartBars.ToIndex - ChartBars.FromIndex. While it's possible to do this in OnBarUpdate, it's not recommended and would be more reliably used in OnRender as it changes based on how the chart is viewed/scrolled/stretched, and OnBarUpdate only runs when the bar updates.

Here's a pair of links to our help guide:
