To prevent this behavior, **set the legends “AutoUpdate” property**. The above line can also be added to the MATLAB startup script if the user wants it to apply it to every MATLAB session.

## How do I turn off the legend in Matlab?

1- **Select the curve you don't want have legend.** **2- Go to the "more properties" (while the curve is still selected).** **3- Turn "HandleVisibility" off**.

## How do I change the legend location in Matlab?

To move the legend to a different tile, **set the Layout property of the legend**. Determined by Position property. Use the Position property to specify a custom location.

## How do you title a figure in MATLAB?

Create Title and Subtitle

Create a plot. Then **create a title and a subtitle by calling the title function with two character vectors as arguments**. Use the ‘Color’ name-value pair argument to customize the color for both lines of text. Specify two return arguments to store the text objects for the title and subtitle.

## How do I create a label in MATLAB?

**Add Title and Axis Labels to Chart**

- title(‘Line Plot of Sine and Cosine Between -2pi and 2pi’)
- xlabel(‘-2pi < x < 2pi’) ylabel(‘Sine and Cosine Values’)
- legend({‘y = sin(x)’,’y = cos(x)’},’Location’,’southwest’)
- k = sin(pi/2); title([‘sin(pi/2) = ‘ num2str(k)])

## How do I make a graph in MATLAB?

**MATLAB – Plotting**

- Define x, by specifying the range of values for the variable x, for which the function is to be plotted.
- Define the function, y = f(x)
- Call the plot command, as plot(x, y)

## How do you plot data in MATLAB?

## How do I save a figure in MATLAB?

Click File > Generate Code…. The generated code displays in the MATLAB Editor. **Save the code by clicking File > Save As**. Generated files do not store the data necessary to recreate the graph, so you must supply the data arguments.

## How do I open a figure in MATLAB?

To display the figure, set visibility to ‘visible’ . If you do not want to display the figure, use the ‘invisible’ setting. You can use this option with any of the input argument combinations in the previous syntaxes. **fig = openfig(___)** returns the figure object.

## How do you label axis in Python?

To set labels on the x-axis and y-axis, **use the plt.** **xlabel() and plt.** **ylabel() methods**.

## How do you print in MATLAB?

**How do I print (output) in Matlab?**

- Type the name of a variable without a trailing semi-colon.
- Use the “disp” function.
- Use the “fprintf” function, which accepts a C printf-style formatting string.

## How do you do log in MATLAB?

**Y = log10( X )** returns the common logarithm of each element in array X . The function accepts both real and complex inputs. For real values of X in the interval (0, Inf ), log10 returns real values in the interval ( -Inf , Inf ). For complex and negative real values of X , the log10 function returns complex values.

## How do you clear in MATLAB?

On Windows platforms, start MATLAB by **double-clicking the MATLAB shortcut icon on your Windows desktop**. On UNIX platforms, start MATLAB by typing matlab at the operating system prompt. You can customize MATLAB startup.

## What is GCF MATLAB?

fig = gcf **returns the current figure handle**. If a figure does not exist, then gcf creates a figure and returns its handle. You can use the figure handle to query and modify figure properties.

## How do you combine strings in MATLAB?

str1 = “Good”; str2 = “Morning”; Combine them **using the append function**. To add a space between the input strings, specify a space character as another input argument. As an alternative, you can use the plus operator to combine strings.

## What is set in MATLAB?

In MATLAB^{®}, the sets are **arrays of numbers, dates, times, or text data**. Most set operations compare sets for exact equality, which can be problematic in the context of floating-point arithmetic.

## What is subplot in MATLAB?

subplot( m , n , p ) **divides the current figure into an m -by- n grid and creates axes in the position specified by p** . MATLAB^{®} numbers subplot positions by row. The first subplot is the first column of the first row, the second subplot is the second column of the first row, and so on.

## How do I save a figure in Python?

If you want to save matplotlib figures as individual files, you can do this with the **savefig function**. If you want to save figures in a single file, use the saveas function instead.
