The advent of the amChart legend

Question

I have amChart with many lines, for example one . The legend looks a little awful.

Is it possible to display a legend on one line with some scrolling? as for columns ? (I do not want to change the container div height)

Answer 1

The question is too old to answer, but it can still help someone quickly get rid of this problem.

The following is the proper documentation provided by amcharts: https://www.amcharts.com/tutorials/putting-a-legend-outside-the-chart-area/

And here is a JsFiddle example: http://jsfiddle.net/amcharts/Cww3D/

HTML:

Chart div:
<div id="chartdiv" style="height: 250px; border: 2px dotted #c33; margin: 5px 0 20px 0;"></div>

<br />
Legend div:
<div id="legenddiv" style="border: 2px dotted #3f3; margin: 5px 0 20px 0;"></div>

JavaScript:

var chart;

var chartData = [{category:" "}];

AmCharts.ready(function() {
    // SERIAL CHART
    chart = new AmCharts.AmSerialChart();
    chart.autoMarginOffset = 0;
    chart.dataProvider = chartData;
    chart.categoryField = "category";
    chart.startDuration = 1;

    // AXES
    // category
    var categoryAxis = chart.categoryAxis;
    categoryAxis.labelRotation = 45; // this line makes category values to be rotated
    categoryAxis.gridAlpha = 0;
    categoryAxis.fillAlpha = 1;
    categoryAxis.fillColor = "#FAFAFA";
    categoryAxis.gridPosition = "start";

    // value
    var valueAxis = new AmCharts.ValueAxis();
    valueAxis.dashLength = 5;
    valueAxis.title = "Visitors from country";
    valueAxis.axisAlpha = 0;
    chart.addValueAxis(valueAxis);

    // GRAPH
    for (var i = 0; i < 15; i ++) {
        chartData[0]["val"+i]  = Math.floor(Math.random() * 20);
        var graph = new AmCharts.AmGraph();
        graph.valueField = "val"+i;
        graph.title = "Graph #"+i;
        graph.type = "column";
        graph.lineAlpha = 0;
        graph.fillAlphas = 1;
        chart.addGraph(graph);
    }

    // LEGEND
    var legend = new AmCharts.AmLegend();
    chart.addLegend(legend, "legenddiv");

    // WRITE
    chart.write("chartdiv");
});

CSS:

body { font-family: Verdana; padding: 15px;}

#legenddiv {
    height: 100px !important; /* force that height */
    overflow: auto;
    position: relative;
}
