google visualization charts - methods and available options to control a chart

[EIEIO]

I am developing a generic multiline chart to chart content from a sql query. In one case the resultset has 8 columns - 3 voltages, 3 currents, 1 watts, 1 power_factor, so I need 4 vertical axes. Using Google visualization linechart, 1 axis is to the left and 3 are to the right. The 3 right-side vertical axes overwrite one another. How can I spread the right side vertical axes so they do not overwrite.

The Google Material Line chart DOES correctly separate the 3 right-side axes, but Material charts do not support lineWidth (I need to turn traces off and on - I can do that in the visualization charts by setting lineWidth to zero) but that property is NOT supported in the Material charts.

Does anyone know:

1. How to hide one or more traces on a Material chart (what property can I set to hide a series, or other method to hide the trace)? or
2. How to spread the right-side vertical axes on a visualization chart (when axis property lets me move the axes around so they do not overlap)?
