javascript - 删除 AmCharts 中的灰色标题框

Question

在图表上绘制一些历史数据时，我偶然发现了这个令人讨厌的灰色框，我无法摆脱它。

基本上我从这个例子开始:http://www.amcharts.com/demos/date-based-data/并做了一些细微的修改(删除了图表滚动条)。

图表使用类型:serial，主题:light。

仍然没有在文档中找到任何内容 http://docs.amcharts.com/3/javascriptcharts/类似于这个。

我尝试过“指南”、“图表”、“chartScrollBar”，但似乎没有任何效果。

感谢任何帮助。

带有灰色标题框的图表:

AmCharts session :

        chart = AmCharts.makeChart("chartdiv", {
            "type": "serial",
            "theme": "light",
            "marginLeft": 0,
            "marginRight": 0,

“灰色框”是图表滚动条。默认情况下图表不显示滚动条。因此，要删除它，只需将其从图表配置中完全删除即可:

chart = AmCharts.makeChart("chartdiv", {
    "type": "serial",
    "theme": "light",
    "marginLeft": 0,
    "marginRight": 0,
    "autoMarginOffset": 0,
    "path": "http://www.amcharts.com/lib/3/",
    "dataDateFormat": "YYYY-MM-DD",
    "valueAxes": [{
        "id": "v1",
        "axisAlpha": 0,
        "position": "left"
    }],
    "balloon": {
        "borderThickness": 1,
        "shadowAlpha": 0
    },
    "graphs": [{
        "id": "g1",
        "bullet": "round",
        "bulletBorderAlpha": 1,
        "bulletColor": "#FFFFFF",
        "bulletSize": 5,
        "hideBulletsCount": 50,
        "lineThickness": 2,
        "title": "red line",
        "useLineColorForBulletBorder": true,
        "valueField": "value",
        "balloonText": "<div style='margin:5px; font-size:19px;'><span style='font-size:13px;'>[[category]]</span><br>[[value]]</div>"
    }],
    "chartCursor": {
        "pan": true,
        "valueLineEnabled": true,
        "valueLineBalloonEnabled": true,
        "cursorAlpha": 0,
        "valueLineAlpha": 0.2
    },
    "categoryField": "date",
    "categoryAxis": {
        "parseDates": true,
        "dashLength": 1,
        "minorGridEnabled": true,
        "position": "bottom"
    },
    "export": {
        "enabled": false
    },
    "dataProvider": chartData
});
