Hello Jeff Kershner,
Thank you for contacting us.
This behavior is intended because of the layout mode of bar charts.
The default layout mode for Bar series type is "Between" and the ticks are between the bars while the label is under the bar.
You can change the layout mode to "Inside" so that the tick is under the bar.
.RC1.DefaultView.ChartArea.AxisX.LayoutMode = AxisLayoutMode.Inside;
Let me know if this helped you out.
