An orange/blue SVG Horizontal Bar chart

An example of a Horizontal Bar chart which has the Y axis centered. The chart has a draw event attached to it so that when the draw() function is called a small bit of text is added to the bottom right of the SVG tag that serves as a label showing what the X axis represents.

This goes in the documents header:
<script src="RGraph.svg.common.core.js"></script>
<script src="RGraph.svg.hbar.js"></script>
Put this where you want the chart to show up:
<div style="padding: 15px">
    <div style="width: 850px; height: 500px" id="chart-container"></div>
This is the code that generates the chart:
    new RGraph.SVG.HBar({
        id: 'chart-container',
        data: [[-.27,-.21],[.06,.07],[0,.07],[.03,.03],[.03,.05],[.04,.06],[-.31,.38],[.09,.08],[-.02,.10],[.12,.11],[.22,.32],[.12,.1]],
        options: {
            marginBottom: 40,
            marginRight: 100,
            hmargin: 20,
            yaxisLabels: [
