NT8 refreshing chart area

[ren37]

Hello

How to refresh some rectangular area on chart? I mean some Invalidate() method to invoke indicator OnRender().

Hello,

Thank you for the question.

You could try using ForceRefresh(), if that does not solve the problem I would suggest posting the reason this is needed as it may be more clear what needs to be done to solve what you are questioning.

This helps, ty.

But in NT7 Plot() method had rect parameter wich was area bounds to redraw.
Redraw all chart might be over and resource intensive.

Hello,

Thank you for the reply.

NinjaTrader 7 and NinjaTrader 8 rendering are very different, NT8 now uses SharpDX for rendering.

The supported method would be ForceRefresh() to queue a refresh of the chart, if that is too much overhead, potentially the logic being used needs to be adjusted?

Can you provide more information on the specific use case? there may be alternative ways to do what you are attempting now that NT8 has more options available on what you can do.

I look forward to being of further assistance.

*250ms is minimal refresh interval.
