MATLAB: Self-organizing map plotting help

Deep Learning Toolboxplottingself-organizing map

I have tried two years to plot Som map (self-organizing map);but I can't do it with matlab
this is my program (I want plot the position of the input [1 0] in the map) please help me
I have read help plotsom, doc , nothing to do this
p1=[1 1]'; p2=[1 2]'; p3=[2 -1]'; p4=[2 -2]'; p5=[-1 2]'; p6=[-2 1]'; p7=[-1 -1]'; p8=[-2 -2]';
P=[p1 p2 p3 p4 p5 p6 p7 p8];
% Create a Self-Organizing Map
dimension1 = 10;
dimension2 = 10; 
net = selforgmap([dimension1 dimension2]);
% Train the Network
[net,tr] = train(net,P); 
% Test the Network
outputs = net(P);
% View the Network
view(net)
%test
A=sim(net,[1 0]);
%plot Som map
axis([0 10 0 10]);
%hold on; plotting A in the Map
circles = plot(A,'ob');

>> szout = size(outputs) % [ 100 8 ]
uniqueout = unique(outputs) % [ 0 1 ]
szout =
   100     8
uniqueout =
     0
     1
>> findones = find(outputs == 1)
findones =
     7
   103
   221
   341
   405
   523
   611
   701
These can be converted to the positions of the training data in the 10 x 10 matrix.
similarly,
>> size(net([ 1 0]))
ans =
   100     2
You can calculate the position .
However, I cannot make any sense of most of the plotsom routines.
Sorry,
