A demo showing range markers on a scatter plot. Here we've added one marker to each axis, but each axis supports multiple markers if required. The demo also makes use of a custom color source to allow highlighting of the data values that fall within the intersection of the marked ranges.
To illustrate the item label support for this chart, you can click on a data point to display an item label for that item (use shift-click if you would like to add item labels to multiple data points).
