Getting the Bar Range in View

[stoner]

How can you determine which bar indexes in the Bars are currently being displayed in a charts view?

For example, say I have 450 bars in the chart Dataset and bars 325 - 345 are currently being displayed in my chart view. What API do I use to determine that range?

Hello stoner,

This would be part of the ChartBars object:

You can find examples of this system being used in various indicators that come with the platform, this is generally used from OnRender for rendering purposes.

The Chart documentation may be of interest as well, the various chart components contain the convience methods for when you are working with OnRender/coordinate based systems.

I look forward to being of further assistance.
