Graph curve missing

[couchroach]

I am building a little canvas element that contains a line graph. However, whilst it shows up in the simulator the line remains stubbornly missing when deploying to my Vertical. Any ideas?

  ctx.strokeStyle = '#0000FF';
  ctx.lineWidth = 2;
  
  ctx.beginPath();
  for (i = 0; i < graphValues.length; i++) {
    x = left + width * i / (graphValues.length - 1);
    value = graphValues[i];
    y = graphBottom - (
      (value - MEAN_LEVEL) * amplitudeScale / 1.80 + 0.5
    ) * height;
    y = Math.max(graphTop, Math.min(graphBottom, y));

    if (i === 0) {
      ctx.moveTo(x, y);
    } else {
      ctx.lineTo(x, y);
    }
  }

Ok, seems like the watch only renders 12 points, not 96… For now I’ll use a stepped line.
