I just made a little test application using the .NET 6 Preview 6 and MAUI with chart control to see if we can use it for a future project. I was able to display just a basic chart with 1000 points in it, in ascending order on X axis. But the performance is really not there when running on my Android 10 device. I only made a Zoom at factor 2 and use panning right to left and it's not smooth at all. There is nothing in the chart (no grid, no annotations). Just a simple 2 axis chart. I can really not go with this because there will be many more data in our product at the chart need to be fast enough. Maybe it's a settings somewhere that need to be adjusted... Take a note that I was able to run the chart in WinUI project and the performance is correct, but I am on a very fast PC, it is just normal to be fast. Note: There is some kind of deceleration effect when panning, I want to disable it but not found how.
Anyway, it will be really cool if you can provide a very simple MAUI test application with the fastest full screen chart with Pan/Zoom with 1000 points (which for me is really not much data) and the corresponding code to me to validate if your library can do the job. I know that MAUI and .NET 6 is not released yet, but performance should be there now because it's really close to bug fixing only state now. Thanks.
