How are you creating the donut chart?

I’m not sure what you mean but if you want to stop the user from zooming the page displayed in the web viewer add user-scalable in the meta tag in the .html header

< meta name = “viewport” content = “width=device-width, initial-scale=1, user-scalable=no” />

This is an example with html code. in photo I mark how to set a specific size value. The background can also be changed.

.c3 svg {height:350px;} body {background-color: #69BD43;}

Are you using c3 or chartJS?

You can write your text on the canvas directly, and that may be a better long term solution more scalable across devices.
