A combined Bar and Line chart

If you like RGraph please share it:

This goes in the documents header:
<script src="RGraph.svg.common.core.js"></script>
<script src="RGraph.svg.bar.js"></script>
<script src="RGraph.svg.line.js"></script>
, Put this where you want the chart to show up:
<div style="width: 650px; height: 300px" id="chart-container"></div>
This is the code that generates the chart:
<script>
    new RGraph.SVG.Bar({
        id: 'chart-container',
        data: [[-43,14],[57,-44],[-64,-16],[56,-36],[21,-89],[-39,-41],[-78,-10]],
        options: {
            yaxisTextSize: 10,
            yaxisLabelsCount: 10,
            yaxisMin: -100,
            yaxisMax: 100,
            hmargin: 10,
            colors: ['rgba(255,0,0,0.2)','rgba(0,200,200,0.2)'],
            gutterLeft: 50,
            labelsAbove: true,
            labelsAboveSize: 8
        }
    }).draw();


    new RGraph.SVG.Line({
        id: 'chart-container',
        data: [19,-88,71,66,93,-96,55],
        options: {
            spline: true,
            backgroundGrid: false,
            gutterLeft: 50,
            yaxisMax: 100,
            yaxisMin: -100,
            yaxis:false,
            yaxisScale: false,
            xaxis: false,
            hmargin: 40,
            filled: true,
            filledColors: ['rgba(0,200,200,0.25)'],
            colors: ['#0bb'],
            linewidth: 3,
            tickmarksStyle: 'filledcircle',
