# How do I change the properties of an axis in Matlab?

## How do I change the properties of an axis in Matlab?

To change the units, set the FontUnits property. MATLAB automatically scales some of the text to a percentage of the axes font size. Titles and axis labels — 110% of the axes font size by default. To control the scaling, use the TitleFontSizeMultiplier and LabelFontSizeMultiplier properties.

## How do I manage axis in Matlab?

Specify Axis Limits

- Set the maximum x-axis limit to 0 and the minimum y-axis limit to -1.
- Control the direction of increasing values along the x-axis and y-axis by setting the XDir and YDir properties of the Axes object.
- By default, the x-axis and y-axis appear along the outer bounds of the axes.

**How do I change the width of an axis in Matlab?**

go to edit -> axes properties and this will open up a property inspector. within this select “box styling” option and see the value for “LineWidth”. By changing this, you will be able to change the thickness of the axes in the figure.

### How do I make axis values bold in Matlab?

XAxis. Color = ‘r’; % Make the x axis only have a font size of 14 and text weight of bold, and color blue. ylabel(‘Y Axis’, ‘FontSize’, 14, ‘FontWeight’, ‘bold’);

### How do I change the axis scale in Matplotlib?

Change x axes scale in matplotlib

- Using plt. plot() method, we can create a line with two lists that are passed in its argument.
- Add text to the axes.
- Using xticks method, get or set the current tick locations and labels of the X-axis.
- To show the figure, use plt.

**How do you change the scale on a graph in Matlab?**

Direct link to this comment

- In matlab, the scale is called the c-axis. In order to manipulate the scale, you must manipulate the c-axis values.
- type in the command window:
- caxis([0 0.1]) or whatever you want you scale limits to be.

## What can you do with the Axis command in Matlab?

axis mode sets whether MATLAB® automatically chooses the limits or not. Specify the mode as manual , auto , or one of the semiautomatic options, such as ‘auto x’ . axis ydirection , where ydirection is ij , places the origin at the upper left corner of the axes. The y values increase from top to bottom.

## How do I change axis labels in Matlab?

Add Title and Axis Labels to Chart

- title(‘Line Plot of Sine and Cosine Between -2\pi and 2\pi’)
- xlabel(‘-2\pi < x < 2\pi’) 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 you change the width of a line in Matlab?**

Direct link to this answer

- To plot two lines with different line widths, you can use either of these approaches.
- Return the two “Line” objects as an output argument from the “plot” function and then set the “LineWidth” property for each.
- Use the “hold on” command to plot the two lines separately.

### How do I make font bold in Matlab?

boldObj = Bold() creates a bold object that specifies to use bold for a text object. boldObj = Bold( value ) if value is true , creates a bold object that specifies to use bold for a text object.

### What is Axis tight in Matlab?

axis tight sets the axis limits to the range of the data. axis fill sets the axis limits and PlotBoxAspectRatio so that the axes fill the position rectangle. This option has an effect only if PlotBoxAspectRatioMode or DataAspectRatioMode are manual . axis ij places the coordinate system origin in the upper-left corner.

**How do I get axis limits in MATLAB?**

Use Semiautomatic Axis Limits. Set the maximum x-axis limit to 0 and the minimum y-axis limit to -1. Let MATLAB choose the other limits. For an automatically calculated minimum or maximum limit, use -inf or inf, respectively. [X,Y,Z] = peaks; surf(X,Y,Z) xlabel(‘x-axis’) ylabel(‘y-axis’) xlim([-inf 0]) ylim([-1 inf])

## What is axis in MATLAB?

axes is the low-level function for creating axes graphics objects. axes creates an axes graphics object in the current figure using default property values. axes(‘PropertyName’,PropertyValue,…) creates an axes object having the specified property values. MATLAB uses default values for any properties that you do not explicitly define as arguments.

## How do you plot a scatter plot in MATLAB?

To produce scatter plots, use the MATLAB ® scatter and plot functions. lsline(ax) superimposes a least-squares line on the scatter plot in the axes specified by ax instead of the current axes (gca).
