I'm trying to add data to a plotchart after the dataprovider
has been set. For example, suppose I have this data, bound to a
plotchart. Data looks great. But, I have additional data I want to
add programmatically. In order to differentiate it from the already
bound data, I want to add it to a new series. How do I do this? You
can see my attached code with my attempt, but it doesn't work. Am I
doing something wrong?
