I’m currently using the CanvasJS react component. I tried to add the code from the JSFiddle into the the componentDidMount life cycle method after this.chart.render() is called. It’s not working as expected. When I debug right after this call the horizontal lines that I just drew on the canvas are visible but the actual data series is not yet. Then the data series is drawn and the the horizontal lines disappear. What am I missing? is the canvas cleared asynchronously when drawing the dataseries?
