automatically when in Examine mode.

If this option is selected Spectro Pro will draw vertical bars from the
horizontal axis to each data point. The bar width in pixels can be set in
the width field.

If this option is selected, Spectro Pro will draw the vertical bars of a bar
graph with shadows, giving an illusion of depth.

A gridline for every tick mark can be displayed if desired. The color and
