I'm putting together an M-file where I include several group scatter plots. For unknown reasons, I'm unable to pre-determine the legend location (NorthEastOutside). I can determine the location after the plot is created by manually editing the figure properties.
Is this a limitation of the function?

Cyclist, I was able to answer my own question.
Lets say we use the Mathworks example for the gscatter function:
http://www.mathworks.com/help/stats/gscatter.html
load discrim; gscatter(ratings(:,1),ratings(:,2),group,'br','xo');
This yields the gscatter plot at the link above.
By issuing the following, I can now place the legend in the desired location.
>> legend('data1','data2','location','Northeastoutside')
However, the group IDs are not the same as before (1 and 2 versus data 1 and data 2). I was hoping to find a way where I could relocate the legend without losing the original group IDs. I can maintain the original IDs by placing the legend manually - using the edit figure properties.
Have you run into this before?

The current answer is no.
Using the same example as above, the gscatter command will not allow the user to pre-position the legend. One workaround is to find the handle to the legend object and set the legend to the desired position.
load discrim figure, gscatter(ratings(:,1),ratings(:,2),group,'br','xo', [], 'on') % Find the handle to the legend object and set position l= findobj(gcf,'tag','legend'); set(l,'location','northeastoutside');

It is easier to just silence the auto legend in gscatter by setting doleg as "off" Next, add the legend. Example:
gscatter(c2,c1,my_labels,my_color,'o+',[],'off');
legend(unique(char(my_labels),'rows'),'location','best')
