java.lang.IllegalArgumentException：纹理必须为非空（CanvasJs 和 JavaFX）

Question

我目前正在使用 JavaFX 和 CanvasJS 来显示图形

我有几个显示点的图表

我有 JS 变量，其中包含每个图形的点（您可以通过在 HTML 输入中输入值和日期来逐个修改点）

JS点列表中修改点时我只更新我们做了点修改的Canvas

（我还尝试通过在每个 CanvasJS.Chart 实例上调用 render () 函数来刷新所有 Canvases）（之前我在JS中只用全局变量来装点现在，当我更新图表时，这些点位于局部变量中我测试是否 undefined 尽量不再有错误）

然而，当我修改图表上的点时它起作用了但是当滚动并将点放在其他图形上时，出现以下错误：

在我看来这些是已知错误：https://bugs.java.com/bugdatabase/view_bug.do?bug_id=8092801

虽然我不明白如何解决它

我使用的Java版本是jdk1.8.0_202 （网站上指出它是从版本 JDK 8u20 开始修复的）（我的客户用 8u281 测试，他仍然有错误）

我的代码如下：

(这是更新图表的JS代码，其他图的函数也修改一个点的值然后更新它们的图）

$(document).on('click','.modifValue1', function()
{
    var dateValue1 = $('input[name="dateValue1"]').val();
    var value1 = parseFloat($('input[name="value1"]').val().replace(",", "."));

    // Dans modifyValue1, on parcoure la liste de points
    // et on modifie le point à la date
    dataValue1Json = modifyValue1(valueGlobalAllPointGraph1, dateValue1, value1);

    displayValue1Json(dataValue1Json);
});

// To update graphe 1
function displayValue1Json(value1){

// As there is a NullPointer error
if(value1 === undefined){
    return;
}

   var chartValue1 = new CanvasJS.Chart("chartContainerValue1",
        {
            zoomEnabled: true,
            legend:
            {
                verticalAlign : 'top',
                horizontalAlign : 'right',
            },
            axisX:{
                valueFormatString: "MM-YYYY" ,
                labelAngle: -50,
                labelFontColor: "black",
                title: "temps",
                gridColor: "#d2d2d2",
                gridThickness: 1
            },
            axisY: {
                labelFontColor: "#328fe1",
                title: "valeur",
                titleFontColor: "#328fe1",
                lineColor: "#328fe1",
                valueFormatString: "####",
                gridColor: "#d2d2d2",
                includeZero: false,
                valueFormatString: "0.00",
            },
            data: [
            {
                type: "line",
                click: onClickPointNullGraph,
                connectNullData: false,
                legendText: "value1",
                    showInLegend: true,
                color: "#328fe1",
                markerSize:3,
                dataPoints:value1
            }
            ]
        });

    chartValue1.render();

    $('div#chargementPage').fadeOut();
}

你有想法吗？

Answer 1

出现错误是因为我显示的图片宽度过大

通过减少宽度，我和客户都没有错误

java.lang.IllegalArgumentException：纹理必须为非空（CanvasJs 和 JavaFX）
