Is it possible to use tiledlayout to create a figure with plots and... (2024)

Yes, it's possible to combine plots and vector images (such as PDF images) within a figure using tiledlayout and nexttile in MATLAB. While nexttile is primarily designed for plotting axes, you can still use it to display images by creating an axes object and then displaying the image within that axes.

Here's a general approach to achieve this:

1. Use a custom MATLAB function extractImagePDF to extract images from a native PDF and save them as JPG files. Follow the MATLAB Answer for code and usage of the custom function at: https://www.mathworks.com/matlabcentral/answers/709623-how-can-i-convert-a-scanned-pdf-to-an-image-using-matlab.
2. Create a tiled layout using tiledlayout.
3. Use nexttile to create an axes for each plot or image.
4. For plots, use standard plotting functions like plot, scatter, etc., to generate the desired plot in each axes.
5. For images, use the imshow function to display the PDF image within the axes.
6. Optionally, add titles to the plots and images using the title function.

Here's an example code snippet demonstrating this approach, after generating a JPG/PNG image:

This code will create a figure with three subplots displaying sine, cosine, and tangent waves, and a fourth subplot displaying the image of a cat. Finally, it will export the figure as a PDF named plot_and_image.pdf.

Hope it helps!

Hi AP,

Using "tiledlayout" in MATLAB, you can create a figure that includes both plots and images.But MATLAB doesn't support PDF images for this purpose, you can leverage external tools to convert pdf to an image format (such as PNG/JPG) and then display it using the "imshow" or "imagesc" function within the "tiledlayout"

I tried the implementation with a demo image and this was the output:

Hope this helps.
