        @sispheor Is everything invisible or just the gauge?
        Do you see pressure or temperatures?
        What is in your console.log from

        console.log('adafruit_python_bpm.py results: %j', results[0]);

          @Charley Yes the table is visible. Only the gauge doesn’t appear.

            Okay I might have an idea

            Change your createElement part to

            let mycanvas = document.createElement("div");
            mycanvas.id=("divcanvas")
            let target=document.getElementById("divcanvas")

                Uncaught TypeError: Cannot read property 'getContext' of null

                  Maybe you could try this

                  let mycanvas = document.createElement("canvas");   // changed from div to canvas
                  mycanvas.id=("divcanvas")
                  let target=document.getElementById("divcanvas")
                  

                  I made a typo yesterday

                      I tried with another lib called canvas-gauges. It’s the same. The canvas doesn’t appear on the screen
                      0_1522616850740_invisible_canvas.png

                      I’m wondering if a parent CSS config or something like could be the reason.

                        It’s good it works!! For the last lib I just forgot to call the draw method.
