Javascript 我能'；t使用JChartFX在多Y轴和日期X轴图表中显示任何内容

我想画一张有三个Y轴和一个日期X轴的图表。解析Json时，我有以下数据数组：

var items = [
    {"CoplanarIrradiance": 760,"AirTemperature": 35,"SurfaceTemperature": 32,"Time": "2014-Apr        27T18:15:00"}, {"CoplanarIrradiance": 460,"AirTemperature": 25,"SurfaceTemperature": 31,"Time": "2014-Apr-27T18:30:00"}, {"CoplanarIrradiance": 341,"AirTemperature": 27,"SurfaceTemperature": 32,"Time": "2014-Apr-27T18:45:00"}, {"CoplanarIrradiance" 233,"AirTemperature": 31,"SurfaceTemperature": 32,"Time": "2014-Apr-27T19:00:00"}, ... ]

但我不需要画图表。它只显示X轴，这是不正确的。 这是我的代码：

                     chart1.setDataSource(data);    


        // Eje de Tiempo (X)
        var axis = chart1.getAxisX().getLabelsFormat().setFormat(cfx.AxisFormat.Date);
        chart1.getAxisX().getLabelsFormat().setCustomFormat(";MMM-dd");

        // Eje de Coplanar Irradiance(Y)
        var axis1 = chart1.getAxisY();
        axis1.getTitle().setText("Coplanar Irradiance (W/m2)");
        axis1.getGrids().getMajor().setVisible(false);
        axis1.getDataFormat().setFormat(cfx.AxisFormat.Number);
        axis1.getDataFormat().setDecimals(2);

        // Eje de Air Temperature (Y)
        var axis2 = chart1.getAxisY2();
        axis2.getTitle().setText("Air Temperature (C)");
        axis2.setPosition(cfx.AxisPosition.Near);
        axis2.getGrids().getMajor().setVisible(false);
        chart1.getAxisY2().getDataFormat().setFormat(cfx.AxisFormat.Number);
        axis2.getDataFormat().setDecimals(2);

        // Eje de Surface Temperature (Y)
        var axis3 = new cfx.AxisY();
        chart1.getAxesY().add(axis3);
        axis3.getTitle().setText("Surface Temperature (C)");
        axis3.setVisible(true);
        axis3.setPosition(cfx.AxisPosition.Far);
        axis3.getLabelsFormat().setFormat(cfx.AxisFormat.Number);
        axis3.getDataFormat().setDecimals(2);

        // Especificamos que hay tres series de datos.
        chart1.getData().setSeries(3);

        var series1 = chart1.getSeries().getItem(0);
        var series2 = chart1.getSeries().getItem(1);
        var series3 = chart1.getSeries().getItem(2);

        series1.setAxisY(axis1);
        series2.setAxisY(axis2);
        series3.setAxisY(axis3);

        series1.setGallery(cfx.Gallery.Lines);
        series2.setGallery(cfx.Gallery.Lines);
        series3.setGallery(cfx.Gallery.Lines);

        // ----Assign data fields--------
        var fields = chart1.getDataSourceSettings().getFields();

        var field = new cfx.FieldMap();
        var field2 = new cfx.FieldMap();
        var field3 = new cfx.FieldMap();

        field.setName("CoplanarIrradiance");
        field.setUsage(cfx.FieldUsage.Number);
        fields.add(field);

        field2.setName("AirTemperature");
        field2.setUsage(cfx.FieldUsage.Number);
        fields.add(field2);

        field3.setName("SurfaceTemperature");
        field3.setUsage(cfx.FieldUsage.Number);
        fields.add(field3);

        var legendBox = chart1.getLegendBox();
        legendBox.setDock(cfx.DockArea.Bottom);
        legendBox.setContentLayout(cfx.ContentLayout.Center);

        // ----Set Sample Data------------
        var divHolder = document.getElementById('meteo_pop_up_grafica_imagen');
        chart1.create(divHolder);

这是结果图表：

有什么问题？数据集是正确的

提前感谢

我只能看到您使用的代码有一两个问题：

数据源中的日期时间字段必须符合ISO 8601格式yyyy MM ddTHH:MM:ss.fffZ，例如2014-04-27T18:15:00.000Z

据我所知，您只提供了数据源的一小部分样本，原始数据源可能包含跨越几天的日期。如果是这种情况，则在X轴中使用日期格式是正确的。但是，如果您希望传递较小的数据集，并主要关注时间而不是日期，则应该格式化X轴以使用时间

代码的其余部分工作得非常好。使用jChartFX的最新版本和下面的代码（这几乎是您的代码，上面提到了两个更改），我得到了预期的图表

var items = [
    { "CoplanarIrradiance": 760, "AirTemperature": 35, "SurfaceTemperature": 32, "Time": "2014-04-27T18:15:00.000Z" },
    { "CoplanarIrradiance": 460, "AirTemperature": 25, "SurfaceTemperature": 31, "Time": "2014-04-27T18:30:00.000Z" },
    { "CoplanarIrradiance": 341, "AirTemperature": 27, "SurfaceTemperature": 32, "Time": "2014-04-27T18:45:00.000Z" },
    { "CoplanarIrradiance": 233, "AirTemperature": 31, "SurfaceTemperature": 32, "Time": "2014-04-27T19:00:00.000Z" }
];


chart1.setDataSource(items);

// Eje de Tiempo (X)
var axisX = chart1.getAxisX();
axisX.getLabelsFormat().setFormat(cfx.AxisFormat.Time);

//var axis = chart1.getAxisX().getLabelsFormat().setFormat(cfx.AxisFormat.Date);
//chart1.getAxisX().getLabelsFormat().setCustomFormat(";MMM-dd");

// Eje de Coplanar Irradiance(Y)
var axis1 = chart1.getAxisY();
axis1.getTitle().setText("Coplanar Irradiance (W/m2)");
axis1.getGrids().getMajor().setVisible(false);
axis1.getDataFormat().setFormat(cfx.AxisFormat.Number);
axis1.getDataFormat().setDecimals(2);

// Eje de Air Temperature (Y)
var axis2 = chart1.getAxisY2();
axis2.getTitle().setText("Air Temperature (C)");
axis2.setPosition(cfx.AxisPosition.Near);
axis2.getGrids().getMajor().setVisible(false);
chart1.getAxisY2().getDataFormat().setFormat(cfx.AxisFormat.Number);
axis2.getDataFormat().setDecimals(2);

// Eje de Surface Temperature (Y)
var axis3 = new cfx.AxisY();
chart1.getAxesY().add(axis3);
axis3.getTitle().setText("Surface Temperature (C)");
axis3.setVisible(true);
axis3.setPosition(cfx.AxisPosition.Far);
axis3.getLabelsFormat().setFormat(cfx.AxisFormat.Number);
axis3.getDataFormat().setDecimals(2);

// Especificamos que hay tres series de datos.
chart1.getData().setSeries(3);

var series1 = chart1.getSeries().getItem(0);
var series2 = chart1.getSeries().getItem(1);
var series3 = chart1.getSeries().getItem(2);

series1.setAxisY(axis1);
series2.setAxisY(axis2);
series3.setAxisY(axis3);

series1.setGallery(cfx.Gallery.Lines);
series2.setGallery(cfx.Gallery.Lines);
series3.setGallery(cfx.Gallery.Lines);

// ----Assign data fields--------
var fields = chart1.getDataSourceSettings().getFields();

var field = new cfx.FieldMap();
var field2 = new cfx.FieldMap();
var field3 = new cfx.FieldMap();

field.setName("CoplanarIrradiance");
field.setUsage(cfx.FieldUsage.Number);
fields.add(field);

field2.setName("AirTemperature");
field2.setUsage(cfx.FieldUsage.Number);
fields.add(field2);

field3.setName("SurfaceTemperature");
field3.setUsage(cfx.FieldUsage.Number);
fields.add(field3);

var legendBox = chart1.getLegendBox();
legendBox.setDock(cfx.DockArea.Bottom);
legendBox.setContentLayout(cfx.ContentLayout.Center);

确保您使用的是最新的位

我希望这有帮助。

我应该如何设置Y轴或X轴的时间（hh:mm:ss）格式的最大值？
