When working with MATLAB, it can be frustrating to constantly adjust the height of your axes to fit your data. Fortunately, MATLAB provides a simple solution to this problem by allowing you to set a default axes height. By setting a default height for your axes, you can save time and ensure that your plots consistently fit within your desired dimensions.
To set the default axes height in MATLAB, you will need to use the set command and modify the DefaultAxesPosition property. The DefaultAxesPosition property determines the position and size of the axes within the figure window. By modifying this property, you can set a default height for the axes that will be used for all subsequent plots.
Here is an example of how you can set the default axes height in MATLAB:
set(groot, ‘DefaultAxesPosition’, [left bottom width height])
In the above example, replace left, bottom, width, and height with the desired values for your axes position. The left and bottom values specify the distance from the bottom-left corner of the figure window, while the width and height values specify the size of the axes.
By setting a default axes height in MATLAB, you can streamline your workflow and ensure that all of your plots are consistently sized. Experiment with different values for the axes position to find the dimensions that work best for your specific needs.
Understanding Default Axes Height
In MATLAB, the axes are an essential component of plotting and visualizing data. By default, when you create a figure and plot data, the axes are automatically generated with a default height.
The default axes height is determined by several factors, including the size of the figure and the desired aspect ratio of the plot. MATLAB tries to optimize the axes height to provide a balanced and visually pleasing representation of the data.
However, in some cases, you may want to modify the default axes height to better fit your specific requirements or preferences. Fortunately, MATLAB provides several ways to accomplish this.
Method 1: Modify the Figure Size
One way to change the default axes height is to modify the size of the figure. By increasing or decreasing the figure’s height, you can indirectly affect the axes height. However, this approach may also affect other elements in the figure, such as the title, labels, or legends.
Method 2: Adjust the Axes Position
Another approach is to directly adjust the position of the axes within the figure. MATLAB provides the Position property of the axes object, which allows you to specify the position and size of the axes. By modifying the height component of the position, you can change the axes height while preserving the aspect ratio.
Method 3: Use the ‘outerposition’ Property
The ‘outerposition’ property of the axes object provides an alternative way to set the axes height. This property represents the position of the axes within the figure, including any whitespace or borders around the axes. By modifying the height component of the ‘outerposition’, you can adjust the axes height while keeping the surrounding area intact.
It’s important to note that modifying the default axes height may require some experimentation to achieve the desired results. You may need to adjust other parameters, such as the font size or tick labels, to ensure the plot remains visually appealing.

Overall, understanding how to set the default axes height in MATLAB gives you greater control and flexibility in creating visualizations that effectively communicate your data.
What is Default Axes Height?
In MATLAB, the default axes height refers to the height of the plotting area in a figure. The axes height determines how much vertical space is available for displaying plots and other graphical elements.
When you create a new figure or subplot in MATLAB, the default axes height is typically set to a default value. This default value is determined by the MATLAB software and can vary depending on factors such as the size of the figure window and the number of subplots.
By default, the axes height is automatically adjusted to fit the contents of the plot. However, in some cases, you may want to set a specific height for the axes to achieve the desired visual appearance.
Adjusting Default Axes Height
To adjust the default axes height in MATLAB, you can use the “Position” property of the axes object. The “Position” property specifies the position and size of the axes within the figure window.
For example, to set a specific height for the axes, you can modify the “Position” property as follows:
figure
axes('Position', [x y width height])
In the above code, “x” and “y” specify the position of the lower-left corner of the axes within the figure, while “width” and “height” specify the dimensions of the axes. By adjusting the “height” value, you can change the default axes height.
It’s important to note that modifying the default axes height can affect the overall layout of the figure and the alignment of multiple subplots. Therefore, it’s recommended to carefully consider the impact of the changes on the visual appearance of the plots.
Why is Default Axes Height Important?
In Matlab, the default axes height plays a crucial role in creating visually appealing and informative plots. The axes height determines the vertical space allocated to the plot area, including the x and y axes and any associated labels or titles.
Setting an appropriate default axes height is important to ensure that the plot is not cramped or too spacious, as this can affect the readability and interpretation of the data. When the axes height is too small, it may lead to overlapping labels or an overcrowded plot, making it difficult to distinguish between different data points.
On the other hand, setting the axes height too large can result in wasted space, reducing the efficiency of displaying the data. It can also lead to larger file sizes when exporting plots, especially when working with multiple subplots.
By setting a sensible default axes height, you can strike a balance between maximizing the use of space and maintaining clarity in the visualization. This can enhance the overall appearance of the plot and make it easier for the audience to interpret the data.
Moreover, having a consistent default axes height across different plots can help maintain visual consistency and make it easier to compare and contrast multiple visualizations. It can also save time and effort when creating and modifying plots, as you won’t need to scale the axes height manually for each plot.
Considering the importance of default axes height in creating effective visualizations, it is worthwhile to spend some time experimenting and fine-tuning this parameter to achieve optimal results.
Setting Default Axes Height in MATLAB
When creating plots in MATLAB, it’s important to consider the size and dimensions of the axes, as it can significantly impact the visual representation of the data. By default, MATLAB automatically adjusts the height of the axes to fit the plot, but sometimes it’s necessary to set a specific default height for all plots.
To set the default axes height in MATLAB, you can use the DefaultAxesFontSize property. This property allows you to specify the font size of the axes labels and tick marks. By adjusting the font size, you can indirectly control the height of the axes. Here’s an example:
set(groot, 'DefaultAxesFontSize', 12);In this example, we set the default font size of the axes to 12. As a result, the height of the axes will be adjusted to accommodate the larger font size.
It’s important to note that changing the default font size will affect all plots created afterwards, but it won’t affect plots that have already been created. To apply the change to all plots, you may need to regenerate them or manually adjust the axes properties.
In addition to DefaultAxesFontSize, there are other properties that you can modify to adjust the default height of the axes. These include:
DefaultAxesTickLength: can be used to adjust the length of the tick marks on the axes, which indirectly affects the height of the axes.DefaultAxesLabelFontSizeMultiplier: can be used to adjust the size of the axes labels relative to theDefaultAxesFontSize.DefaultAxesTitleFontSizeMultiplier: can be used to adjust the size of the axes title relative to theDefaultAxesFontSize.
By carefully adjusting these properties, you can set a default height for the axes that best suits your needs and enhances the visual representation of your data.
Step 1: Accessing the Axes Property
To set the default height of the axes in MATLAB, you need to access the axes property called “Position”. This property allows you to control the position and size of the axes within the figure window.
You can access the Position property of an axes object using the dot notation. For example, if you have an axes object named “ax”, you can access its Position property by typing ax.Position.
The Position property is a four-element vector representing the position and size of the axes in the form [left bottom width height]. The values are specified in normalized units, ranging from 0 to 1, where [0 0 1 1] represents the full size of the figure window.
To set the default height of the axes, you need to modify the fourth element of the Position vector, which represents the height. For example, to set the height to 0.5 (50% of the figure window height), you can use the following code:
ax.Position(4) = 0.5;This code sets the height of the axes represented by the “ax” object to 0.5. You can adjust the value as per your requirement.
Step 2: Modifying the Axes Height
In this step, we will modify the height of the axes to set it as the default height for all subsequent plots.
To modify the axes height, we will use the set function and specify the desired height value. The height is determined by the 'Position' property of the axes object, which is a four-element vector representing the position of the axes in the figure window.
First, let’s create a new figure and axes:
figure;
axes;Next, we will use the set function to modify the axes height:
set(gca, 'Position', [0.1, 0.1, 0.8, 0.8]);The gca function returns the current axes object, and we pass it as the first argument to set. The second argument is the 'Position' property, which is set to a four-element vector. The first element represents the horizontal position of the axes, second element represents the vertical position, third element represents the width, and fourth element represents the height.
In this example, we have set the height to 0.8, which means that the axes will occupy 80% of the available vertical space in the figure window. You can adjust this value according to your requirements.
By modifying the axes height in this way, you can ensure that all subsequent plots will have the desired height.
Here is the complete code for modifying the axes height:
figure;
axes;
set(gca, 'Position', [0.1, 0.1, 0.8, 0.8]);Now you are ready to move on to the next step, where we will learn how to save this modified axes height as the default for all plots.
