Download the library code and make sure the +diagrams folder is inside a folder in the MATLAB path.

Example code is shown in usage.m, as well as in the examples folder.

Set up a new figure by running h_fig = diagrams.setup(). Then, add graphics objects to the figure by calling the diagrams library, or by using matlab functions like plot and plot3.

Certain graphics objects must be redrawn depending on the camera angle. At the end of your script, you should call diagrams.redraw(). You can also press any keyboard key to call diagrams.redraw() if you're moving the camera position interactively.

To export the figure, call, name, location). This will save the figure in both .eps and .svg format.

The figure is designed to be displayed 3.5 in wide to fit the width of an IEEE journal article. However, there is a 2x scaling factor so that the MATLAB figure window is a reasonable size on a computer screen. To include the figure in LaTeX, you should use \includegraphics[scale=0.5, clip]{diagram.eps}. Adding clip makes sure any white space doesn't overlap with text.

If you're submitting to arXiv and want to use pdfLaTeX, you will need to convert the eps files to pdf files. arXiv doesn't do this conversion. If you have miktex installed, run the command

miktex-epstopdf --outfile=diagram-converted-to.pdf diagram.eps

Or, run the following bash file on Windows:

for %%I in (*.eps) do (
    miktex-epstopdf --outfile="%%~nI-converted-to.pdf" "%%I"

Then, you can include the PDF file using \includegraphics[scale=0.5, clip]{diagram-converted-to.pdf}

Creating GIFs

Method 1: exportgraphics()

To make sure the gif stays the same size, make a rectangle that fills the whole frame.

annotation('rectangle',[0 0 1 1]);

You may want to use campos(), camva(), and camtarget() to lock the camera view.

At the end of the animation loop, use exportgraphics to save each frame to a file.

exportgraphics(gca, "filename.gif", "Append", i ~= 1)

Method 2: imwrite()

This method gives more control over delay time and other options.

filename = "file_name.gif";
clear im
for i = 1:N
    % Code here
    frame = getframe(h_fig);
    im{i} = frame2im(frame);

for idx = 1:length(im)
    [A, map] = rgb2ind(im{idx}, 256);
    if idx == 1
        imwrite(A, map, filename, "gif", "LoopCount", Inf, "DelayTime", 0.5);
        imwrite(A, map, filename, "gif", "WriteMode", "append", "DelayTime", 0.5);
