MATLAB: I want to create a plot using X Y coordinates

coordinatesplot

I have 51 nodes that each one of them has X Y coordinates. I used the command: plot(x,y, 'd') but I would like the figure to show me the number of each node next to the diamond.For example the first node I'd like to have the number 1 next to it, the second the number 2 etc. Also I'd like the first node to be different shape or colour from the others. Do I have to use two different types of plot or it can be done in the same command? Thank you for your time.

Use the text function.
Example: — 
x = rand(1,5);
y = rand(1,5);
nrc = compose('%2d',1:numel(x));                % Coordinate Numbers (Cell Array)
cm = jet(numel(x));                             % Use The ‘colormap’ Of Your Choice
figure
scatter(x, y, 75, cm, 'd', 'filled')
grid
text(x, y, nrc)

Changed from plot to scatter since it provides more options, especially with respect to colouring the points. There are a limited number of shapes, so I would just go with changing the colours. The sizes of the plotted points can chnage with the colours with scatter.
