To get or create a .fig file in Matlab, you can follow these steps:
- Open the figure you want to save as a .fig file in the Matlab Figure Window.
- Once the figure is displayed, go to the File menu at the top of the Figure Window.
- From the File menu, select the "Save As" option. This will open a dialog box.
- In the dialog box, navigate to the directory where you want to save the .fig file.
- Specify a name for the file, including the .fig extension at the end (e.g., "myfigure.fig").
- Click on the "Save" button to save the figure as a .fig file.
By following these steps, you can easily get or create a .fig file in Matlab. The .fig file format is specific to Matlab and allows you to save figures in a way that preserves all the graphical elements, settings, and properties for future use or modifications.

How to save a figure as a .fig file in MATLAB?
To save a figure as a .fig file in MATLAB, you can follow these steps:
- Open the figure window that you want to save.
- Use the savefig function to save the figure. Syntax: savefig(fig_handle, 'file_name.fig') fig_handle is the handle of the figure you want to save. 'file_name.fig' is the desired name of the .fig file. It is recommended to include the .fig extension in the file name. For example, to save the current figure as 'my_figure.fig', you can use: savefig(gcf, 'my_figure.fig');
Note that the gcf function is used to obtain the handle of the current figure. If you have the handle of the specific figure you want to save, you can use it instead of gcf.
- The figure will be saved to your current working directory or the directory specified in MATLAB's "Current Folder" window.
By saving a figure as a .fig file, you can load and access the figure data and properties later using MATLAB's openfig or hgload functions.
How to convert a .fig file to a vector-based format in MATLAB?
To convert a .fig file to a vector-based format in MATLAB, you can follow these steps:
- Open the .fig file using the openfig function. This function returns a handle to the figure.
1
|
figHandle = openfig('your_figure.fig');
|
- Export the figure to a vector-based format using the saveas function. Specify the figure handle and the desired output file name with the appropriate extension (e.g., '.eps', '.pdf', '.svg', '.emf', '.png', etc.).
1
|
saveas(figHandle, 'output_file.svg', 'svg');
|
- Close the figure to release the memory.
1
|
close(figHandle);
|
Make sure to replace 'your_figure.fig' with the actual file name of your .fig file and 'output_file.svg' with the desired output file name.
Note: MATLAB R2019b or later versions support direct export to SVG format using the exportgraphics function. The process is simplified and does not require the use of the openfig and saveas functions.
How to change the background color of a .fig file in MATLAB?
To change the background color of a .fig file in MATLAB, follow these steps:
- Open the .fig file by double-clicking on it or using the openfig function in MATLAB.
- To access the figure properties, select the figure window and go to the "Property Inspector" tab in the MATLAB desktop.
- In the Property Inspector, find the "Color" property of the figure. Click on the color swatch next to the "Color" property.
- Select a color from the color palette or enter the RGB values of the desired color.
- MATLAB will update the background color of the figure immediately.
If you want to change the background color programmatically, you can use the following code:
1 2 3 4 5 6 7 8 9 10 11 12 13 14 |
% Load the .fig file fig = openfig('your_figure.fig'); % Get the handle of the figure's root object fig_root = get(fig, 'root'); % Set the background color to a desired color set(fig_root, 'Color', [r, g, b]); % Replace r, g, b with RGB values % Save the modified figure saveas(fig, 'modified_figure.fig'); % Close the figure close(fig); |
Make sure to replace "your_figure.fig" with the path to your .fig file, and [r, g, b] with the desired RGB values for the background color.
What is the maximum number of figures that can be saved in a .fig file?
There is no specific maximum number of figures that can be saved in a .fig file. The number of figures that can be saved depends on factors such as the file size limit and available memory on the computer. However, it is generally recommended to keep the number of figures in a single .fig file to a reasonable amount to ensure efficient handling and performance.
How to share a .fig file with colleagues who do not have MATLAB?
To share a .fig file with colleagues who do not have MATLAB, you can use the following steps:
- Save the .fig file in a location that is easily accessible to everyone, such as a shared network folder or a cloud storage service.
- Export the .fig file to a standard image format, such as PNG, JPEG, or TIFF, that can be opened by any image viewer. To do this, follow these MATLAB steps: a. Open the .fig file in MATLAB. b. Go to the "File" menu and select "Save As." c. Choose a suitable image format for export (e.g., PNG). d. Specify the location and name for the exported image file. e. Click on the "Save" button to export the .fig file as an image.
- Share the exported image file with your colleagues via email, file-sharing platforms, or any other communication method. They can then view the image using any image viewer or software of their choice.
Note: By exporting as an image, your colleagues won't be able to directly interact with the plot, but they will be able to see the visual representation of the figure.
What is the maximum number of plots that can be included in a .fig file?
There is no specific maximum number of plots that can be included in a .fig file. The number of plots that can be included depends on factors such as the memory capacity of the system and the size and complexity of the plots themselves. In practice, you can include a large number of plots in a .fig file, but if the file becomes too large, it may be difficult to load or manipulate.
