Hi Simon,
create a local html-file at the modules folder with the following content:
Name it as you like (mychart.html for example) and add the path to MMM-SmartWebDisplay instead of the URL you entered before:
url: [“/modules/mychart.html”],
Play around with the red-marked values…the exact data depends on the browser in use.
This way is much easier than to adjust it directly in MMM-SmartWebDisplay.
Greetings
Thomas
