An SVG Waterfall chart using the Google Sheets connector

A Waterfall chart that's being created using the Google Sheets connector. In this case only positive values are being displayed.

This goes in the documents header:
<script src="RGraph.svg.common.core.js"></script>
<script src="RGraph.svg.common.sheets.js"></script>
<script src="RGraph.svg.waterfall.js"></script>
Put this where you want the chart to show up:
<div style="width: 1000px; height: 300px" id="chart-container"></div>
This is the code that generates the chart:
    new RGraph.Sheets('1ncvARBgXaDjzuca9i7Jyep6JTv9kms-bbIzyAxbaT0E', function (sheet)
        var data   = sheet.get('B2:B13'),
            labels = sheet.get('A2:A13');
        for (var i=0; i<labels.length; i+=2) {
            labels[i] = "\n" + labels[i];

        new RGraph.SVG.Waterfall({
            id: 'chart-container',
            data: data,
            options: {
                marginTop: 50,
                textSize: 9,
                xaxisLabels: labels,
                tooltips: labels,
                yaxis: false,
                backgroundGridColor: '#eee',
                backgroundGridVlines: false,
                backgroundGridBorder: false,
                colorsStroke: '#aaa',
                yaxisLabelsCount: 6,
                xaxisColor: '#333',
                title: 'Cumulative total of widgets sold by Brian',
                titleSubtitle: 'Numbers are sales by store only',
                titleSubtitleItalic: true,
                labelsAbove: true,
                labelsAboveUnitsPost: 'pc'
