Position a WPF Path so that its origin is located at the bottom, center of its container

Question

I'm trying to center a Path so that its origin (0, 0) is located at the bottom, center of its container. Assume that the container is a Grid.

---

Example:

Note: the tail of the arrow is at the origin (0, 0). The tail is centered horizontally but the overall arrow is skewed to the left. This is what I want to achieve regardless of which direction the arrow is pointing.

This needs to work for paths where the x and y coordinates are positive, negative, or a mixture of both.

How can this be done via XAML with the least markup?

Here's what I ended up going with. Seems to work, but if there's a cleaner way to do this, I'd love to hear it:

<Grid>
    <Grid.ColumnDefinitions>
        <ColumnDefinition Width="*" />
        <ColumnDefinition Width="*" />
    </Grid.ColumnDefinitions>
    <Path Grid.Column="1"
          HorizontalAlignment="Left"
          VerticalAlignment="Bottom"
          StrokeThickness="1"
          Data="{Binding PathGeometry}" />
</Grid>
