如何显示超过一年的日期

Question

只要我的日期超过one year，amcharts就不会显示图表。我认为（也许）原因是format中的CategoryAxis日期只有Month，如果有一年以上，那就没有意义了，我试着改变它，但它不起作用，所以如何解决它，这是我的代码： （数据是输入的，实际上我不知道fromDate和toDate的实用程序是什么

<script type="text/javascript">

    var mask = '<div class="k-loading-mask" style="width: 100%; height: 100%; top: 0px; left: 0px;"><span class="k-loading-text" style="text-indent: 0; width:60%; top: 40%; left: 20%; background-color: #0F0;">Please wait while the Back Test results are being generated. <br />This could take up to 30 seconds.</span><div class="k-loading-image" style="display:none;"></div><div class="k-loading-color"></div></div>';

    var fromDate = new Date(2016, 2, 1, 0, 0, 0, 0);
    var toDate = new Date(2016, 2, 31, 0, 0, 0, 0);

    AmCharts.ready(function () {
        drawStockChartData();
    });

    function drawStockChartData() {
        $.ajax({
            url: "/Home/TestAmStockChartData",
            type: "POST",
            dataType: "json",
            success: function (result) {
                for (var i = 0 ; i < result.length; i++) {
                    result[i].Date = new Date(parseInt(result[i].Date.slice(6, 19)));
                }
                createStockChart(result);
            },
        });
    }



    function createStockChart(data) {
        var chart = new AmCharts.AmStockChart();


        // DATASETS
        var dataSet1 = new AmCharts.DataSet();
        dataSet1.color = "#b0de09";
        dataSet1.fieldMappings = [{
            fromField: "NAV",
            toField: "NAV"
        },
        {
            fromField: "PNL",
            toField: "PNL"
        }];
        dataSet1.dataProvider = data;
        dataSet1.categoryField = "Date";

        chart.dataSets = [dataSet1];

        // PANELS
        var stockPanel1 = new AmCharts.StockPanel();
        stockPanel1.showCategoryAxis = true;
        stockPanel1.title = "NAV";
        stockPanel1.percentHeight = 100;
        stockPanel1.eraseAll = false;
        //stockPanel.addLabel(0, 100, "Click on the pencil icon on top-right to start drawing", "center", 16);

        var graph1 = new AmCharts.StockGraph();
        graph1.title = "NAV";
        graph1.valueField = "NAV";
        graph1.bullet = "round";
        graph1.bulletColor = "#FFFFFF";
        graph1.bulletBorderColor = "#00BBCC";
        graph1.bulletBorderAlpha = 1;
        graph1.bulletBorderThickness = 2;
        graph1.bulletSize = 7;
        graph1.lineThickness = 2;
        graph1.lineColor = "#00BBCC";
        graph1.useDataSetColors = false;
        graph1.comparable = true;
        graph1.compareField = "HSI";
        stockPanel1.addStockGraph(graph1);

        var stockLegend1 = new AmCharts.StockLegend();
        stockLegend1.valueTextRegular = " ";
        stockLegend1.markerType = "none";
        stockPanel1.stockLegend = stockLegend1;
        stockPanel1.drawingIconsEnabled = true;

        chart.panels = [stockPanel1];

        // OTHER SETTINGS
        var scrollbarSettings = new AmCharts.ChartScrollbarSettings();
        scrollbarSettings.graph = graph1;
        scrollbarSettings.updateOnReleaseOnly = false;
        chart.chartScrollbarSettings = scrollbarSettings;

        var cursorSettings = new AmCharts.ChartCursorSettings();
        cursorSettings.valueBalloonsEnabled = true;
        chart.chartCursorSettings = cursorSettings;

        var panelsSettings = new AmCharts.PanelsSettings();
        panelsSettings.creditsPosition = "bottom-right";
        //panelsSettings.creditsPosition = null;
        panelsSettings.marginRight = 16;
        panelsSettings.marginLeft = 16;
        chart.panelsSettings = panelsSettings;

        // PERIOD SELECTOR
        var periodSelector = new AmCharts.PeriodSelector();
        periodSelector.position = "bottom";
        periodSelector.periods = [{
            period: "DD",
            count: 10,
            label: "10 days"
        }, {
            period: "MM",
            count: 1,
            label: "1 month"

        }, {
            period: "YYYY",
            count: 1,
            label: "1 year"
        }, {
            period: "YTD",
            label: "YTD"
        }, {
            period: "MAX",
            label: "MAX"
        }];
        chart.periodSelector = periodSelector;

        chart.write('divPnlAmChart');
    };

</script>

我测试breakpoint无法进入

function createStockChart(data) {
        var chart = new AmCharts.AmStockChart();

，如果data还有更多内容，则无法显示1 year
