Unable to update annotations dynamically

[QuentinReyn]

Hello everyone,

I'm currently trying to display a min/max annotation on my timeseries chart. It includes two dynamics annotations to do this.

The min/max value is refreshed whenever the zoomEvent is called. So the annotations are updated after a zoom event. And I'm updating them like this :

setAnnotations1(min, max) {
    let newAnnotation: ApexAnnotations = {
      yaxis: [
        {
          y: max,
          label: {
            text: "Max temp : " + max,
            style: {
              background: "black"
            }
          },
          strokeDashArray: 0,
        },
        {
          y: min,
          label: {
            text: "Min temp : " + min,
            style: {
              background: "black"
            }
          },
          strokeDashArray: 0,
        }
      ]
    }
    this.chartOptions1.annotations = newAnnotation;
  }

But unfortunately the annotations aren't refreshed on the chart view. It looks like I need to re-render the chart to get the new annotations, does anyone know if it's possible in a first place to have dynamic annotations ?

Thanks
