Generate Graph Nodes and add buttondown callbacks for interactivity

I’m trying to create a graph that brings up a dialogue box when one of the nodes is clicked. I use
NodeTable = table(‘Size’,[0 4],’VariableTypes’,{‘double’,’string’,’double’,’double’}, …
‘VariableNames’,{‘Code’,’Name’,’Latitude’,’Longitude’});
EdgeTable = table(‘Size’,[0 2],’VariableTypes’,{‘cell’, ‘double’}, …
‘VariableNames’,{‘EndNodes’,’Distance’});

nodetemp = inputdlg(["Node Name", "Latitude", "Longitude"], "Node Details");
%check input present
if isempty(nodetemp)== 0
%check node not present in table
if any(matches(app.NodeTable.Name,nodetemp(1),IgnoreCase=true))==false
%format table and add code in column 1
nodeinp = addvars(cell2table(transpose(nodetemp),’VariableNames’,{‘Name’,’Latitude’,’Longitude’}), app.index, ‘before’, 1,’NewVariableNames’,{‘Code’});
%update graph with node data
app.NodeTable=[app.NodeTable; nodeinp];
app.G=addnode(app.G,nodeinp);
app.map = plot(app.UIAxes,app.G,’NodeLabel’,app.G.Nodes.Name,’EdgeLabel’,app.G.Edges.Distance);%plot graph
%set node coordinates
app.map.XData = str2double(app.NodeTable.Longitude);
app.map.YData = str2double(app.NodeTable.Latitude);

app.index = app.index + 1; %increment node counter
end
end
to create the graph, add nodes and plot it. I then am attempting to use
nodes=findobj(app.map,’Marker’,’o’);
nodesLength = length(nodes);
for count=1:nodesLength
nodes(count).ButtonDownFcn=@(src,event)nodeButtonDown(app,count);
end
to get a hold of the node graphical objects and assign callbacks as advised here but the plot doesn’t seem to generate the nodes as children/separate objects like it says in all the documentation. The nodes variable just becomes a copy of the graphplot object. You’ll notice I’m using the app designer.I’m trying to create a graph that brings up a dialogue box when one of the nodes is clicked.
