I have issues with the selection box of the textannotation in firefox.

Code for the annotation:

    return new TextAnnotation({
    id,
    text: text,
    verticalAnchorPoint: EVerticalAnchorPoint.Center,
    horizontalAnchorPoint: EHorizontalAnchorPoint.Left,
    xCoordinateMode: ECoordinateMode.DataValue,
    yCoordinateMode: ECoordinateMode.DataValue,
    x1: x1,
    y1: y1,
    fontSize: 16,
    fontWeight: "Bold",
    textColor: annotation.color,
    isEditable: isEditable,
    annotationLayer: EAnnotationLayer.AboveChart
})

Please see the differences in the images attached. In the Firefox browser it seems that the svg takes on the size of the scichart surface. Can you help me to fix this problem? The parameters selectionBoxDelta and selectionBoxThickness work in both browsers but do not fix the problem.

Thank you.

I have a chart in the center of the page and the chart will resize according to the browser window size. When I expand the browser window, the chart will expand to fit the browser size. In this case, the chart grows downward gradually (with animation). How can I remove this animation effect when resizing the chart?

In case it’s related to my style. Here are my markup and style for reference:

//Markup

//Style
.contentPanel {
flex: 1 1 auto;
width: calc(100% – 335px);
max-height: calc(100vh – 108px);
display: flex;
flex-direction: column;
}

.chartContainer {
position: relative;
margin: 10px 0;
display: flex;
flex-direction: column;
flex: 1;
}

.scichart-root {
width: 100%;
height: 100%;
}

I am using NextJS with the SciChart trial license for development and suddenly got the error “SciChart: WebGL not supported! ” with Chrome. It worked fine before, and I didn’t change any codes for launching the chart. Also, it works fine with Firefox. The chrome version I am using is 107.0.5304.107.

BTW, the error is gone after I restarted my computer. Is it possible to be related to memory issue?

Below are my codes for initializing the chart:

  const initSciChart = () => {   
    // LICENSING //
           SciChartSurface.setRuntimeLicenseKey("xxx");

           SciChartDefaults.enableResampling = true;
    SciChartDefaults.asyncLabels = true;
    SciChartDefaults.useSharedCache = true;

    drawSpecChart();
};

async function drawSpecChart() {
    // Create the SciChartSurface in the div 'scichart-root'
    // The SciChartSurface, and webassembly context 'wasmContext' are paired. This wasmContext
    // instance must be passed to other types that exist on the same surface.

    let xAxesNumberRange = new NumberRange(0, 18);
    let yAxesNumberRange = new NumberRange(-140, -40);

    const chartDefinition = {
        xAxes: [{
            type: EAxisType.NumericAxis,
            options: {
                axisTitle: "Frequency (GHz)",
                axisTitleStyle: {
                    fontSize: 12,
                    fontFamily: "sans-serif",
                    fontWeight: "bold"
                },
                labelStyle: {
                    fontSize: 12,
                    fontFamily: "sans-serif"
                },
                visibleRange: xAxesNumberRange,
                zoomExtentsRange: xAxesNumberRange,

                },
                labelStyle: {

                }
            }

           };

       const { sciChartSurface, wasmContext } = await chartBuilder.build2DChart("scichart-root", chartDefinition);  

    xAxesNumberRange = null;
