First we require to empty the project by removing factors. Note a tiny x appears when the mouse is place over the factor to be removed (see red circle below).

  • Remove observation from the column zone
  • Remove variable from the row zone
  • Remove ds0.PC1 from the y-axis

The result view should be an empty projection Now you create the required project by * Drag-n-drop the ds0.PC2 factor to the x-axis zone * Drag-n-drop the ds0.PC3 factor to the y-axis zone * Drag-n-drop the sex and species factor to the colors zone
