<p>Public ReadOnly Property ScatterValueAxis() As ValueAxis</p>

The scatter value axis is a horizontal axis, and should only be used when there are scatter series, and only scatter series on the primary axis. When there are a mix of scatter and non-scatter series on the primary axis, the CategoryAxis should be used instead.
