Hi,
Today, Lance (Telerik) updated my sample provided in https://www.telerik.com/forums/radcartesianchart-datetimecontinuousaxis-minimum-and-maximum-are-not-respected to bypass the bug on the Min/Max not taking into account.
I re-updated the sample (attached) with 2 videos. The sample is in line with my business app: 1440 data point per serie (up to 5 series).
The performance of LineSeries are really bad, I'm quite surprised because these are just lines.
However, if you replace the "<chart:LineSeries" in MainPage.xaml to "<chart:SplineSeries", it is like in real-time when changing the date. This is awesome and frankly I do not understand how come it is fast versus LineSeries where it takes 3 to 5 seconds to refresh. You can see the 2 videos.
My only fear is Spline has the following bug https://www.telerik.com/forums/radcartesianchart-weird-rendering
Thanks

Hi Sebastien,
Thank you for the provided videos and project. I will need some time to review in details the performance of both series. In general Line and Spline Series are two different series with different drawing and implementation.
If it is needed, I could try to do the same sample in WinUI. I would assume the rendering engine is similar.
Hi Sebastien,
Regarding to the spline series rendering issue, my colleague Yana logged a bug report on your behalf https://feedback.telerik.com/uwp/1571079-chart-splineseries-rendering-is-not-correct-in-certain-scenarios
Regarding to the chart performance behavior, I reproduced it. As I explained both series have different rendering. I have logged this behavior on your side the the public UI for UWP feedback portal: https://feedback.telerik.com/uwp/1571209-chart-inconsistency-in-rendering-performance-between-line-and-splineseries
I am sorry for the inconvenience.
