    I currently have line chart with time on the x-axis. Upon zooming the chart I am passing the viewPortMin & viewPortMax to make the new network request. Until the request is getting fulfilled I am trying to render a custom loading spinner instead of the chart component. Below is the issue I am getting –

    Uncaught TypeError: Cannot read properties of null (reading ‘style’)
    at t._plotAreaMouseUp
    at t._mouseEventHandler
    at HTMLCanvasElement.<anonymous>

    @arj,

    We are unable to reproduce the issue. Can you kindly create a JSFiddle (or a sample project) reproducing the issue and share it with us so that we can run it locally at our end, understand the scenario better and help you out?

    Try showing a custom button once chart is zoomed instead of the canvas chart. Getting error in this function _plotAreaMouseUp. The below checks throws error –

    if (reRender && this.zoomEnabled && this._zoomButton.style.display === “none”) {
    show(this._zoomButton, this._resetButton);
    setButtonState(this, this._zoomButton, “pan”);
    setButtonState(this, this._resetButton, “reset”);
    }

    I have called chart.destroy in unmount method thats why this._zoomButton was setting up as null.
