是的,這是可能的。

只需添加title屬性categoryAxis

"categoryAxis": { 
    "parseDates": true, 
    "title": "That is the title on the X-axis" 
} 

這裏有一個工作示例:

var chart = AmCharts.makeChart("chartdiv", { 
 
    "type": "serial", 
 
    "theme": "light", 
 
    "dataDateFormat":"YYYY-MM-DD", 
 
    "valueAxes": [ { 
 
    "position": "left", 
 
     "title": "That is the title on the Y-axis" 
 
    } ], 
 
    "graphs": [ { 
 
    "id": "g1", 
 
    "balloonText": "Open:<b>[[open]]</b><br>Low:<b>[[low]]</b><br>High:<b>[[high]]</b><br>Close:<b>[[close]]</b><br>", 
 
    "closeField": "close", 
 
    "fillColors": "#7f8da9", 
 
    "highField": "high", 
 
    "lineColor": "#7f8da9", 
 
    "lineAlpha": 1, 
 
    "lowField": "low", 
 
    "fillAlphas": 0.9, 
 
    "negativeFillColors": "#db4c3c", 
 
    "negativeLineColor": "#db4c3c", 
 
    "openField": "open", 
 
    "title": "Price:", 
 
    "type": "candlestick", 
 
    "valueField": "close" 
 
    } ], 
 
    "chartScrollbar": { 
 
    "graph": "g1", 
 
    "graphType": "line", 
 
    "scrollbarHeight": 30 
 
    }, 
 
    "chartCursor": { 
 
    "valueLineEnabled": true, 
 
    "valueLineBalloonEnabled": true 
 
    }, 
 
    "categoryField": "date", 
 
    "categoryAxis": { 
 
    "parseDates": true, 
 
    "title": "That is the title on the X-axis" 
 
    },
