<p>The symmetrical logarithmic scale is logarithmic in both the
positive and negative directions from the origin.</p>
<p>Since the values close to zero tend toward infinity, there is a
need to have a range around zero that is linear. The parameter
<em>linthresh</em> allows the user to specify the size of this range
(-<em>linthresh</em>, <em>linthresh</em>).</p>
You can’t perform that action at this time.
