GraphWrapAndClear

The GraphWrapAndClear will show new points progressing across the graph. Once the graph is filled, the next point added will cause the graph to be cleared and a new graph will slowly be created as new values are added.

Template Parameters:

  • CAPACITY The maximum number of data points on the graph.
