I would like to know how to get my CustomMapping to run the Apply method. I have a list of animals and the speed of the animals should control the colour of the treemapitem. However when the animals speed changes then the treemap tiles don't change colour but on startup the colours visible. They just never change. When the animals size changes the tiles do reflect the changes. How do I run the Apply method?
