WPF Framework Canvas Automatic Scaling based on largest coordinate in list
Hi.
First of all, thank you for reading!
I have a MVVM WPF application and having some trouble with the Canvas and how to draw shapes that are automatically scaled to the canvas size.
Let's say I have a model Y that contains a list of X. X has a location and my goal is to display all X's in a fixed size canvas using circles.
The location of each X can vary wildly so for every list of X that gets selected I need to use the largest coordinate of the furthest X in that list to scale it so all the X's show up properly on the canvas, the furthest one should be located 10% away from the canvas' border. Assuming (0, 0) is the middle of my canvas the calculation for this should be
I am using the CalcBinding nuget so I can do calculations in my binding, like so:
The problem: I can't seem to use the LargestCoordinate property from the ancestor (which is Y) in my calculation for each X
I can get that property in xaml correctly using:
but cannot use this method in my full calculation:
it just gives a whole lot of XAML binding errors like this one:
Is there any way I can use the LargestCoordinate property from Y in my calculation for each X so I can scale the locations properly?

Is there any way I can use the LargestCoordinate property from Y in my calculation for each X so I can scale the locations properly?
