Is there a way to plot the name of a point on a figure when it is plotted?

Hello,
I need to change this code so that I can plot some of the node names next to the plotted nodes on the figure when it is plotted. (the plot would be of finite elements). Is there a way to do this? Thanks for your time
function PolyMshr_PlotMsh(Node,Element,NElem,Supp,Load) % In order to use the Matlab patch function to plot the entire mesh at once, we create an element connectivity matrix ElemMat that is padded with NaNs
clf; axis equal; axis off; hold on;
Element = Element(1:NElem)'; %Only plot the first block
MaxNVer = max(cellfun(@numel,Element)); %Max. num. of vertices in mesh %
PadWNaN = @(E) [E NaN(1,MaxNVer-numel(E))]; %Pad cells with NaN
ElemMat = cellfun(PadWNaN,Element,'UniformOutput',false);
ElemMat = vertcat(ElemMat{:}); %Create padded element matrix
patch('Faces',ElemMat,'Vertices',Node,'FaceColor','w'); pause(1e-6)
if exist('Supp','var')&&~isempty(Supp)&&~isempty(Load)%Plot BC if specified
plot(Node(Supp(:,1),1),Node(Supp(:,1),2),'b>','MarkerSize',8);
plot(Node(Load(:,1),1),Node(Load(:,1),2),'m^','MarkerSize',8); hold off;
end

The function
text( x, y, string )
will do that.

Yes,
text( x, y, sprintf( '#%i', the_number_of_the_element ) )
where x and y are retrieved from fem.e - I guess
