Hello Daniel,
FillColor is not a DependencyProperty, so this exception is expected in .NET. Change it to a StaticResource instead.
To be more specific to what I think you're attempting to do, you cannot dynamically update at runtime after the chart is rendered. This is a situation because of the nature of the native chart controls, they each have different capabilities when it comes to these options and cannot use a dynamically changing property.
If you want to dynamically change the value, you need to instead Remove and Add the PalleteEntry itself from your custom ChartPallete
myPallette.Entries.Clear();
// your newly created pallete entry
var nextEntry = ...;
myPallette.Entries.Add(nextEntry);
If you need to stick to MVVM, you can do this in a custom-built behavior. If you can do this in code-behind or some code-behind method that will replace the pallete entry as a whole. after this PaletteEntry is updated, you can then re-render the series to adopt the new coloring.
We do not have an example of a custom built-behavior, you can learn how to do this here https://docs.microsoft.com/en-us/dotnet/maui/fundamentals/behaviors
Ultimately, at this time, we do not have an official feature that will let you dynamically change FillColor with a DynamicResource. This is a known feature request and is on our backlog.
