Hi Nicholas,
I understand that you want to export the animated plots created in live script to HTML. As per my understanding, there is no direct option available in MATLAB currently to achieve the same. You could follow the following workaround to achieve the same:
1) Save the animated plot as video file using the "VideoWriter". You can refer to the following MATLAB answer to achieve the same.
2) Open the source HTML code and remove the "img" HTML tag code displaying the static plot.
3) Embed the saved video file into your Live Script using "video" HTML tag. You can refer to the following documentation for the same.
I hope this helps.
