Question

我最近开始使用amchart作为我的一个项目。从有AMchart经验的任何人那里寻求帮助。

我有一个数据集，假设在amchart的平滑线图上显示两个系列。我设法让它显示2系列，但这两个系列不共享相同的x轴。

所以任何想法如何让它共享相同的x轴。我已附上以下代码。在图片中，有一行json，由我的代码中的函数load_dashboard_leads（）返回。

 <script>
        var chart;
        var graph;
        var leadsGrowthData = <?PHP echo load_dashboard_leads();?>

            AmCharts.ready(function () {
                // SERIAL CHART
                chart = new AmCharts.AmSerialChart();

                chart.dataProvider = leadsGrowthData;
                chart.marginLeft = 10;
                chart.categoryField = "month";
                chart.dataDateFormat = "MMMM";

                // listen for "dataUpdated" event (fired when chart is inited) and call zoomChart method when it happens
                chart.addListener("dataUpdated", zoomChart);

                // AXES
                // category
                var categoryAxis = chart.categoryAxis;
                categoryAxis.parseDates = false; // as our data is date-based, we set parseDates to true
                categoryAxis.minPeriod = "MM"; // our data is yearly, so we set minPeriod to YYYY
                categoryAxis.dashLength = 3;
                categoryAxis.minorGridEnabled = true;
                categoryAxis.minorGridAlpha = 0.1;

                // value
                var valueAxis = new AmCharts.ValueAxis();
                valueAxis.axisAlpha = 0;
                valueAxis.inside = true;
                valueAxis.dashLength = 3;
                chart.addValueAxis(valueAxis);

                // GRAPH
                graph = new AmCharts.AmGraph();
                graph.type = "smoothedLine"; // this line makes the graph smoothed line.
                graph.lineColor = "#d1655d";
                graph.negativeLineColor = "#637bb6"; // this line makes the graph to change color when it drops below 0
                graph.bullet = "round";
                graph.bulletSize = 8;
                graph.bulletBorderColor = "#FFFFFF";
                graph.bulletBorderAlpha = 1;
                graph.bulletBorderThickness = 2;
                graph.lineThickness = 2;
                graph.valueField = "lead";
                graph.balloonText = "[[category]]<br><b><span style='font-size:14px;'>[[value]]</span></b>";
                chart.addGraph(graph);
                
                // Customer GRAPH
                graph2 = new AmCharts.AmGraph();
                graph2.type = "smoothedLine"; // this line makes the graph smoothed line.
                graph2.lineColor = "#225F6A";
                graph2.negativeLineColor = "#637bb6"; // this line makes the graph to change color when it drops below 0
                graph2.bullet = "round";
                graph2.bulletSize = 8;
                graph2.bulletBorderColor = "#FFFFFF";
                graph2.bulletBorderAlpha = 1;
                graph2.bulletBorderThickness = 2;
                graph2.lineThickness = 2;
                graph2.valueField = "customer";
                graph2.balloonText = "[[category]]<br><b><span style='font-size:14px;'>[[value]]</span></b>";
                chart.addGraph(graph2);

                // CURSOR
                var chartCursor = new AmCharts.ChartCursor();
                chartCursor.cursorAlpha = 0;
                chartCursor.cursorPosition = "mouse";
//                chartCursor.categoryBalloonDateFormat = "YYYY";
                chart.addChartCursor(chartCursor);

                // SCROLLBAR
                var chartScrollbar = new AmCharts.ChartScrollbar();
                chart.addChartScrollbar(chartScrollbar);

                chart.creditsPosition = "bottom-right";

                // WRITE
                chart.write("leadsgrowth");
            });

            // this method is called when chart is first inited as we listen for "dataUpdated" event
            function zoomChart() {
                var monthNames = ["January", "February", "March", "April", "May", "June",
                    "July", "August", "September", "October", "November", "December"
                  ];

                  var d = new Date();
                // different zoom methods can be used - zoomToIndexes, zoomToDates, zoomToCategoryValues
                chart.zoomToCategoryValues(monthNames[d.getMonth()], monthNames[d.getMonth()-12]);
            }

强烈建议您从AmCharts网站的软件包启动项目并下载准备离线模式的示例...

当你定义标题和id时，其工作的不同名称

        var durationGraph1 = new AmCharts.AmGraph();
        durationGraph1.id = "g1";
        durationGraph1.title = "g1";
        durationGraph1.valueField = "value1";
        chart.addGraph(durationGraph1);

        var durationGraph2 = new AmCharts.AmGraph();
        durationGraph2.id = "g2";
            durationGraph2.title = "g2";
            durationGraph2.valueField = "value2";
            chart.addGraph(durationGraph2);

然后使用：

 chartData.push( {
                          date: d3,                       
                          date2: strdate ,
                          value1: distance,
                          value2: distance2
                        } );

在您的函数中生成数字

如果你想要动画，你必须设置：

.amcharts-graph-g2 {
  stroke-linejoin: round;
  stroke-linecap: round;
  stroke-dasharray: 500%;
  stroke-dasharray: 0 \0/;    /* fixes IE prob */
  stroke-dashoffset: 0 \0/;   /* fixes IE prob */
  -webkit-animation: am-draw 40s;
  animation: am-draw 40s;
}
            .amcharts-graph-g22 {
  stroke-linejoin: round;
  stroke-linecap: round;
  stroke-dasharray: 500%;
  stroke-dasharray: 0 \0/;    /* fixes IE prob */
  stroke-dashoffset: 0 \0/;   /* fixes IE prob */
  -webkit-animation: am-draw 40s;
  animation: am-draw 40s;
}

解决此问题的一种方法是：升级到AMCharts ver 3的最新版本
