[Chartjs]-Image pointStyle doesn't load on initial chart render?

It should work if you define the Image inside the component constructor…

constructor() {
  super();
  const myImage = new Image(25, 35);
  myImage.src = "/img/myimage.svg";

and create the Scatter chart inside the render method.

render() {
  return (
    <div>
      <Scatter
        data={this.state.chartData }
        options={this.state.chartOptions}
        ...
      />
    </div>
  );
}
