You can target each series (data column) to a different vertical axis, and there are more than 2 vertical axes. 0 is the left, 1 is the right, and everything else is on the right also, but currently overlaid in the same place as axis 1, so it is best to turn off the display of additional axes. You'll need to set the viewWindow min and max of each axis to align values as you want.
Actually, there is another way to 'flip' how the area and column charts draw their areas. The always draw relative to the baseline value, which defaults to 0. So if you set your baseline to the top of the chart, the areas will be above the data values. You can set a different baseline value for each axis, though this really needs to be a per series option. Concerning the performance, more series add more legend items, but that should not be a significant overhead. There is much more overhead in trying to support interaction with each series, so if you turn off interaction, it may work better. Other than that, I am not sure what might be happening, and we'd have to investigate to find out. You might be able to avoid using separate series, however, if you just add null values to break up the lines (and disable interpolateNulls). If you want different colors for each, you can use the 'style' role to give each line its own color.
