Hi Allen, Its difficult to know what is the problem without knowing what type of object is 'Disease.FL'. plot() is a generic function and it will act differently depending on the type of object you are passing to it. As always, you should provide 'provide commented, minimal, self-contained, reproducible code' so we can find the problem.
As a general comment, you can do any number of plots on a device (a window or a pdf file). The limit is only given by the number and size of the plots and the size of the device.
