<pre>      PASS         &lt;slope&gt;                    FIELD            SHARE? N
      PASS         &lt;intercept&gt;                FIELD            SHARE? N
      GOSUB    0CD .AXIS SYNC Y AXIS
      *        Check for error
      IF       0CD .AXIS SYNC Y AXIS          NE

</pre>
---++ Description:

This subroutine sets a linear formula to synchronize the secondary y-axis scale to the primary y-axis scale.

This is usually used if the two y-axes represent the same measurement using different units. Examples including temperature in Celsius and in Fahrenheit, and length in meters and feet.

<div id="_mcePaste">The formula is :</div> <div id="_mcePaste">y2 = y1 * slope + intercept</div>

Both parameters are optional, and if not received, &lt;slope&gt; defaults to 1 and &lt;intercept&gt; default to zero. To "un-synchronize" the 2 axes, pass a blank for &lt;slope&gt;. If neither parameter is received, this will simply duplicate the scale on both the primary and secondary axes.
