I have been trying to learn how to use Live charts for a School project where I need to be able to graph Large amounts of data. My code gets the data from a file and puts it into a linked list(points) where it is then copied into the Chartvalues Data Structure. using a resource dictionary I have filled the area under the line with white so I could test whether it graphed or not
