      • getLinesVisible

        public java.lang.Boolean getLinesVisible()
        Deprecated.
        As of 1.0.7, use the per-series and base level settings.
        Returns a flag that controls whether or not lines are drawn for ALL series. If this flag is null, then the "per series" settings will apply.
