writing/exporting a plot into a file

Hi,

I currently have a program that uses the plot function to generate a graph. I would like to write the graph into a document. I am very new to matlab and coding in general, and so far have been unable to locate the relevant documentation.

Newer releases: see exportgraphics() https://www.mathworks.com/help/matlab/ref/exportgraphics.html

Older releases: see getframe() https://www.mathworks.com/help/matlab/ref/getframe.html?s_tid=doc_ta or print() https://www.mathworks.com/help/matlab/ref/print.html or saveas() https://www.mathworks.com/help/matlab/ref/saveas.html?searchHighlight=saveas&s_tid=srchtitle

Also, if it is for a "document", see the Report Generator product.

These links have been really helpful, I also have been looking at the ones mentioned here about putting multiple pdfs into one document. https://www.mathworks.com/matlabcentral/answers/745882-multiple-plots-to-one-pdf

You may be able to clarify something,

When I plot something say plot(x, y) I get a figure (graph that I can view), but as far as I understand plot(x, y) is not an obj. Since an obj is any type of axes, figure, etc. Therefore something like

exportgraphics(plot(x, y), 'filenamehere.pdf');

is invalid (to my understanding).

If I had two columnar vectors (arrays) x and y and I wanted to use export graphics I would need to somehow turn them into an obj (a broad term). What type of function or command would I utilize to accomplish this?

plot() returns an array of "primitive chart line" objects. Surfaces, images, lines, patches, text, are the traditional low level objects; there are now a lot of additional low level objects built around a new layer of even lower level objects
