Comment changer le titre de la fenêtre de ce graphe ?

Quelle commande dois-je ajouter, et/ou quelles modifications dois-je apporter pour la changer ?

Answer 1

Vous devez d'abord créer une figure vide avec la commande suivante.

figure('name','Title of the window here');

En faisant cela, la figure nouvellement créée devient votre figure active. Immédiatement après avoir appelé une plot() il imprimera votre tracé sur cette figure. Votre fenêtre aura donc un titre.

Voici le code que vous devez utiliser :

figure('name','Title of the window here');

Answer 2

Vous devez définir figure propriétés.

Au tout début du script, appelez

figure('name','something else')

Appel à figure est une bonne chose, de toute façon, car sans elle, vous tracez toujours dans la même fenêtre, et parfois vous pouvez vouloir comparer deux fenêtres côte à côte.

Alternativement, vous pouvez stocker le handle de la figure en appelant

figH = figure;

afin que vous puissiez modifier ultérieurement les propriétés de la figure à votre convenance (la fonction 'numberTitle' le réglage de la propriété élimine le texte "figure X")

set(figH,'Name','something else','NumberTitle','off')

Jetez un coup d'œil à la propriétés des figures dans la documentation MATLAB pour voir ce que vous pouvez encore modifier si vous le souhaitez.

Answer 3

On peut aussi le faire de cette façon :

figure(xx);
set(gcf, 'name', 'Name goes here')

gcf récupère la poignée de la figure actuelle.

Answer 4

Si vous ne voulez pas inclure dans votre code script (comme conseillé par d'autres personnes ci-dessus), alors vous pouvez simplement faire ce qui suit après avoir généré la fenêtre de la figure :

1. Allez à "Editer" dans la fenêtre de la figure

2. Allez dans "Propriétés de la figure".

3. En bas, vous pouvez taper le nom que vous voulez dans le champ "Figure Name". Vous pouvez décocher la case "Show Figure Number".

C'est tout.

Bonne chance.
