Hi All, I am trying to draw a polar dendrogram by the following code in the app designer but it does not work because it seems that UIAxes doesn't support polar dendrogram. I tried to set a panel as handle but it showed error. This code works with the "dendrogram" function. Can you please have a look on my code?
X = rand(1000,4);
Z = linkage(X,'ward');
estclustnum = 6; % estimated number of clusters
color = Z(end-estclustnum+2,3)-eps;
app.UIFigure.HandleVisibility = 'on';
set(0, 'CurrentFigure', app.UIFigure);
set(app.UIFigure,'CurrentAxes',app.UIAxes);
polardendrogram(Z,0,'ColorThreshold',color);zoom(app.UIAxes,1);
hold(app.UIAxes,'on');set(app.UIAxes,'XTickLabel',[],'XTick',[]);
app.UIFigure.HandleVisibility = 'off';

dendrogram only works with old figure/axes, but you can use copyobj to deal with it. Below a callback for a button in a simple app.
function ButtonPushed(app, event)
X = rand(10,3);
tree = linkage(X,'average');
fig = figure('Visible', 0);
den = dendrogram(tree);
copyobj(den, app.UIAxes);
delete(fig)
end
You will get something like that...
