Interface to produce plotting with specified Y-ranges

This page provides the ability to plot any selection of the OMNI parameters listed below, while specifiying a Y-axis range for each selected parameter. Click left boxes to select output parameter(s), and enter desired Y-scale minimum and maximum values in the boxes to the right of selected parameter(s).
