Answer 1

Edit/Update: As mentioned in the comments, the 5px value can more accurately be just half of whatever your line width value is, I belive default is 2px so in that case you would just want padding: { top: 1 }

There a layout.padding attribute you can set either in options or global. I had this same problem and set

options: {
  layout: {
    padding: {
      top: 5
    }
  },
  ...
}

worked fine for me to not cut off the line http://www.chartjs.org/docs/#chart-configuration-layout-configuration

I used hardcode, just wide draw area at top and bottom. This code based on original Chart.canvasHelpers.clipArea.

const WIDE_CLIP = {top: 2, bottom: 4};

Chart.canvasHelpers.clipArea = function(ctx, clipArea) {
    ctx.save();
    ctx.beginPath();
    ctx.rect(
      clipArea.left,
      clipArea.top - WIDE_CLIP.top,
      clipArea.right - clipArea.left,
      clipArea.bottom - clipArea.top + WIDE_CLIP.bottom
    );
    ctx.clip();
};

You can try clip:false option, worked for me.

Example:

options: {
    clip: false,
    responsive: true,
    interaction: {
      intersect: false,
      mode: 'index',
    }
 }
