1.简单示例1 线条图

<script type="text/javascript" src="../src/plugins/jqplot.canvasTextRenderer.min.js"></script>
<script type="text/javascript" src="../src/plugins/jqplot.canvasAxisLabelRenderer.min.js"></script>

$(document).ready(function(){
  var plot1 = $.jqplot ('chart1', [[3,7,9,1,4,6,8,2,5]]);
});

2.简单示例2 柱状图

$(document).ready(function(){
    // For horizontal bar charts, x an y values must will be "flipped"
    // from their vertical bar counterpart.
    var plot2 = $.jqplot('chart2', [
        [[2,1], [4,2], [6,3], [3,4]],
        [[5,1], [1,2], [3,3], [4,4]],
        [[4,1], [7,2], [1,3], [2,4]]], {
        seriesDefaults: {
            renderer:$.jqplot.BarRenderer,
            // Show point labels to the right ('e'ast) of each bar.
            // edgeTolerance of -15 allows labels flow outside the grid
            // up to 15 pixels.  If they flow out more than that, they
            // will be hidden.
            pointLabels: { show: true, location: 'e', edgeTolerance: -15 },
            // Rotate the bar shadow as if bar is lit from top right.
            shadowAngle: 135,
            // Here's where we tell the chart it is oriented horizontally.
            rendererOptions: {
                barDirection: 'horizontal'
            }
        },
        axes: {
            yaxis: {
                renderer: $.jqplot.CategoryAxisRenderer
            }
        }
    });
});
