我正在使用 amcharts 绘制一个有吸引力的图表。我想在一个图中绘制多个折线图。但是我的代码只画了一张图。当我为第二个折线图添加代码时,由于错误,它没有显示任何内容。我如何在其中添加第二条折线图。这是 .js 文件。
var chart = AmCharts.makeChart("chartdiv", {
"type": "serial",
"theme": "light",
"marginTop":0,
"marginRight": 80,
"dataProvider": [{
"D": "100",
"value": 10
}, {
"D": "200",
"value": 20
}, {
"D": "200",
"value": 30
}, {
"D": "400",
"value": 40
}, {
"D": "500",
"value": 50
}],
"graphs": [{
"id":"g1",
"balloonText": "[[category]]<br><b><span style='font-size:14px;'>[[value]]</span></b>",
"bullet": "round",
"bulletSize": 8,
"lineColor": "#d1655d",
"lineThickness": 2,
"negativeLineColor": "#637bb6",
"type": "smoothedLine",
"valueField": "value"
}],
"chartCursor": { /* required for zoom effect */
"cursorAlpha": 0,
"valueLineEnabled":true,
"valueLineBalloonEnabled":true,
"valueLineAlpha":0.5,
"fullWidth":true
},
/*show x axis values on graph*/
"categoryField": "D",
});
chart.addListener("rendered", zoomChart);
if(chart.zoomChart){
chart.zoomChart();
}
function zoomChart(){
chart.zoomToIndexes(Math.round(chart.dataProvider.length * 0.4), Math.round(chart.dataProvider.length * 0.55));
}
