I am using Matlab online basic for occasional tasks. First of, my thanks for providing a free version of Matlab online.

I recently noticed, that plotting is not working anymore. I get an empty figure each time I plot anything. The issue started on August first with the change of the release Version to R2025a. I know that for certain as i wanted to test the new polarplot compability with the patch function.

Is this a known issue or might that be something concerning my local java version? Any tip is welcome.

Tuve el mismo inconveniente recientemente al usar MATLAB Online: al ejecutar el código, las figuras aparecían vacías. Hoy logré resolverlo borrando los datos de navegación (cookies en navegador Chrome) y luego cerrando sesión. Al volver a ingresar, la herramienta volvió a mostrar correctamente las gráficas. Espero que esta solución también te sea útil.

Today I managed to solve it by deleting the browsing data (cookies in Chrome browser) and then logging out. Upon logging back in, the tool correctly displayed the graphs again. I hope this solution is also useful to you.
