I am coriuous about to make three axis "y" in a graph (mean with error plot in columns). I tried to do but it is imposible. Could you help me about that. Thanks.
on the dialog where you make the means plot, select the "options 2" tab. there is an option for the "x-y axis position". change it to "reversed" and the x and y axes are reversed.
you can do the same for an existing graph with the graph customization dialog. the same option is on the graph layout tab.
