I’ve been trying to get SciChart to work with good performance and as part of my experimentation am trying to see how RenderPriority.Manual works. As far as I can tell, it doesn’t.
I haven’t been able to find much in terms of samples or docs. According to the little documentation here:
https://www.scichart.com/documentation/v4.x/SciChart.Charting~SciChart.Charting.Visuals.RenderPriority.html
It says
Manual — Never redraws automatically. You must manually call
InvalidateElement() or ZoomExtents() on the SciChartSurface in order
to get it to redraw
Now, when I try to call either of those functions on my SciChartSurface, nothing visually happens. I’ve tried other Invalidate methods as well, and still no refresh love.
I’ve attached the small sample application that repro’s the issue.
Please let me know what I’m doing wrong.
Thanks,
Brian

I am considering applying server-side licensing for my javerScript application.
In the document below, there is a phrase “Our server-side licensing component is written in C++.”
(https://support-dev.scichart.com/index.php?/Knowledgebase/Article/View/17256/42/)
However, there is only asp.net sample code on the provided github.
(https://github.com/ABTSoftware/SciChart.JS.Examples/tree/master/Sandbox/demo-dotnet-server-licensing)
I wonder if there is a sample code implemented in C++ for server-side licensing.
Can you provide c++ sample code?
Also, are there any examples to run on Ubuntu?

Hi Andrew. Thanks for the quick answer and while I appreciate the sentiment, I’m curious how to get the feature to work at all. The main reason I’m trying to do this is as an RnD exercise in increasing performance. I’ve asked the question about my situation here (https://www.scichart.com/questions/question/multiple-chart-performance-in-wpf-slows-down-considerably-when-mouse-is-moved#sabai-entity-content-9936) and this Manual approach is another idea I had to try to alleviate mouse issues. If you have an answer for that, we can discuss in that question thread. Otherwise, I’m curious what I’m doing wrong with RenderPriority.Manual.
