In a Continuous Line chart, we see an endless sea of data and then the Series Legend (typically to the right). Our users would like to be able to click one of the items in the Series Legend and then ONLY show the data for what was selected. It's possible to do this with filters/highlighting, but it doesn't work as expected. Even with filtering enabled, it acts like highlighting.

In my attachment, you can see that one item is selected, but which one is it? Ideally, we would ONLY see the data for the selected item.
