The ignore series attribute allows you to plot a series that does not influence the scaling modes. This is useful when plotting boundary lines or a bias on a simulation wave that is using stripChart or scope.

In the below example, the blue line that is drawn from 0-100 does not affect the scaling, allowing the sine wave to scope across the plot.

<timePlot name="myPlot">
  <series name="wave" />
  <series ignore="true">
    <data>0 1; 100 1</data>

<simulation name="sim" duration="100">
        <sine bias="1" />
      <probe ref="sectionName.myPlot.wave" />
