I would like to create a chart showing nutrient concentrations in
multiple lakes according to depth. I would like a single y-axis
showing depth, and multiple x-axis to show some data that's grouped
near 100 and other data that's grouped near 20 to appear close
together, rather than the annoying standard huge gap between 20 and
100. Also, I would like to have multiple horizontal sections on the
chart to graph the other lakes on the same chart.
