You can specify whether the chart shows from right to left or from left to right using the FlowDirection property.
In XAML
Locate the opening <c1:C1OrgChart> tag and insert FlowDirection="RightToLeft" into the tag. The <c1:C1OrgChart> markup should resemble the following:
<c1:C1OrgChart x:Name="_orgChart" Orientation="Horizontal" FlowDirection="RightToLeft">
In the Properties Window
1. Locate the FlowDirection property in the Properties window.
2. Use the drop-down list to change the value to "RightToLeft".
