The MDS plot displays the multidimensional scaling in two dimensions. Below the plot are two buttons to flip the axis either in the vertical or horizontal direction. The MDS solution can be reflected, rotated, or translated without changing the inter-point proximities. The rotating or reflection of the axes is most common when working with geographical objects that have a known map orientation.
If more than two dimensions were used in the analysis, then you can toggle the dimensions shown in the plot using the Select Dimension controls below the plot. The first control defines the horizontal axis of the plot, and the second control defines the vertical axis of the plot.
