Generate plots inside docker container

Hi all,

I'm having some issues generating plots inside a docker container, I'm using a Matlab docker image from 2020b.

I have created a dummy function that generates an invisible plot from a JSON file, which is saved into the current directory and is working fine outside the docker environment. I have then packed the function as a stand-alone application using the Application compiler (result_json_png.exe), entailing I'm only executing the executable inside the container.

However, when I'm trying to generate it inside the container it throws back Error 126, "Unable to load bundle mwosgserver_bultinmpl.dll, Error: 126: not connected. And I'm assuming that it can't render the figure using OpenGL inside the container.

I don't know if there is a solution for this, is it possible to configure the runtime using "painter" in the startup.m file (does it even exist in the runtime)? Is there some setting you can apply as an additional parameter that is passed to the MCC?

Best,

Hi @Petter Cedell

You can use 'painters' in the very beginning of the MATLAB function that plots the figure.

>> set(0, 'DefaultFigureRenderer', 'painters');
