Steelseries.js gauge

Hi all,
I have found steelseries.js java library, and am looking for info how to use it in habpanel widgets?

I found a lot of information, and i have read that habpanel is using angularjs and the lib is in javajs

demo website :

and html 5 canvas is not supported in habpanel ?

I created a html page and displayed into a widget

i have the folowing files in the /conf/html folder :
my files :

  • rds2.css
  • meter.html
  • meter.js

libs :

  • steelseries-min.js
  • steelseries.js
  • tween-min.js
  • tween.js

Habpanel widget

	<iframe  id="frame" class="d-flex flex-column justify-content-center flex-grow-1" style="position: absolute; top: 10px; left: 10px; width: calc(100% - 20px); height: calc(100% - 20px);" src="/static/meter.html" frameborder="no" scrolling="no" ></iframe>

Have some one a linkt that explains how to use .js into habpanel




That’s an excellent post, I wish I understood more of it… :frowning_face:

I’m completely shooting in the dark here, but is what you’re looking for anything to do with how Item values are used in SVG files?

Thanks for your respons.

I have to look again into this topic, but i all ready searched the forum om using .js into habpanel.
I found some solutions, for some parts of the main question.
