title: JSXGraph : How to create sliders outside of the box
body: <p>I am using the JSXGraph library for an application. I know how to use the default sliders that come with the library. However, what I'd like to know is how to use my own sliders that I created and that lie outside of the board to be linked to the graph.</p>
  
  <p>thanks,</p>
