A = randn(5);

hold on;
plot (x,y,'kx');
A = randn(5);

Adding ParallelCoordinatesPlot to axes is not supported. Turn hold off.

I think you have to embed the point in the parallel data. Parallel plots are not meant to be thought of as Cartesian plots.
x=5;y=-1.5;
A = randn(3,5);
A(end+1,:)=nan; A(end,x)=y; %embed x,y in A
p=parallelplot(A,'groupData',[1,1,1,2],'Color',{'blue','red'});
p.MarkerStyle={'none','o'};
p.MarkerSize(end)=10;
