I have a line chart like below
[![enter image description here](https://i.stack.imgur.com/yUAHf.png)](https://i.stack.imgur.com/yUAHf.png)

As you can see there is a gap between 0-0.7.I want to put an indicator like below

[![enter image description here](https://i.stack.imgur.com/pRjsY.png)](https://i.stack.imgur.com/pRjsY.png)

So the expected one is this

to draw something on the chart ,ChartJs has annotations and I tried something like below but couldnt set interval to draw lines

```
   annotation: {
  annotations: [{
            drawTime: 'afterDraw', // overrides annotation.drawTime if set
            id: 'a-line-1', // optional
            type: 'line',
            mode: 'vertical',
            scaleID: 'y-axis-0',
    value: 0,
    borderColor: '#000',
            borderWidth: 2,
        }]
  }

```

There are no accepted values like yMax and yMin on line drawing so I couldnt figure it out how to do that.I'd be appreciate if someone could help me with this.
