amChart legend appearance

István picture István · Jun 6, 2014 · Viewed 9.9k times · Source

I have an amChart with many rows, like this one. The legend looks a bit awfull.

Is it possible to display the legend in a single row with some scrolling? like for the columns? (I don't want to change the container div's height)

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

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

And here is the 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;
}
