Proprietà degli oggetti grafici

Visualizzare e impostare le proprietà degli oggetti grafici, definire i valori predefiniti

È possibile controllare il comportamento e l'aspetto di un particolare oggetto grafico impostandone le proprietà. Per impostare le proprietà, restituire l'oggetto come argomento di output della funzione che lo crea. Ad esempio, la funzione plot restituisce un oggetto grafico lineare. Utilizzare quindi la notazione a punti per visualizzare e impostare le proprietà.

p = plot(1:10,1:10);
p.LineWidth = 3;

In alternativa, è possibile impostare le proprietà utilizzando gli argomenti della coppia nome-valore al momento della creazione dell'oggetto, come plot(1:10,1:10,'LineWidth',3). La maggior parte delle funzioni di plottaggio supporta gli argomenti della coppia nome-valore.

Modify Graphics Objects
This example shows how to create, display, and modify graphics objects in MATLAB®.
Graphics Object Hierarchy
Graphics objects are the visual components used by MATLAB^® to display data graphically.
Access Property Values
You can set and query property values or return them to their original (factory default) values.
Default Property Values
Nearly all graphics object properties have predefined values, but you can define default property values.
Multilevel Default Values
This example sets default values on more than one level in the hierarchy.
Default Values for Automatically Calculated Properties
When you create a graph, MATLAB sets certain property values appropriately for the particular graph.
How MATLAB Finds Default Values
All graphics object properties have values built into MATLAB. You can also define your own default values.
Factory-Defined Property Values
Plotting functions use factory-defined property values if you do not specify values as arguments or as defaults.
