title: LiveCharts: symmetrical Y-graph around the zero axis
body: <p>With LiveCharts I create an X/Y graph:</p>
  <ul>
  <li>X-axis: Time</li>
  <li>Y-axis: symmetrical values output from the zero axis to MinValue and MaxValue.</li>
  </ul>
  <p>The min/max values are set as follows:</p>
  <pre><code>if (Math.Abs(newValueY) &gt; maxValueY)
  {
      maxValueY = Math.Abs(newValueY);
      MaxValue = maxValueY;
      MinValue = -maxValueY;
  }
  </code></pre>
  <p>My problem is that the grid is not displayed symmetrically. The zero axis is not displayed. Is there any way to configure LiveCharts to draw the grid up and down from zero axis instead of starting at MinValue?</p>
  <p>Thanks for any hints!
