Hy everyboby, I would like that in the second tab "evaporazione_mensile" changes the graph with pop-up menù. I wrote the function called "Lista_anniValueChanged", and I would like it changes the graph, but I can't do it and the graph is always the same.
Best regard Dario

app.Lista_anni.Value return a char, you need to modify the comparison like this
if ( value=='1' )
plot(app.UIAxes2,1:3,5:7,'r')
else ( value=='2' )
plot(app.UIAxes2,1:3,5:7,'b')
end
