Recently, I have been working to integrate the Stacked Area and Stacked 100% Area charts into our application; however, in doing so, I have found a bug. In order to re-create this bug, you can pull the chart example from your website-provided samples (it's actually a really great test case).

Re-Create the Bug
To re-create the bug, "choose" a series in the JSON and set a number of the data points to 0 (I chose "Stacked 2", as seen in the embedded javascript, below, pulled directly from your site) and re-render the chart.

Code:
    <script lang="javascript" type="text/javascript">
        $(document).ready(function () {
            $('#jqChart').jqChart({
                title: { text: '100% Stacked Area Chart' },
                animation: { duration: 1 },
                shadows: {
                    enabled: true
                },
                axes: [
                    {
                        type: 'category',
                        location: 'bottom',
                        categories: ['A', 'B', 'C', 'D', 'E', 'F', 'G']
                    }
                ],
                series: [
                    {
                        type: 'stacked100Area',
                        title: 'Stacked 1',
                        data: [62, 70, 68, 58, 52, 60, 48],
                        labels: {
                            font: '12px sans-serif'
                        }
                    },
                    {
                        type: 'stacked100Area',
                        title: 'Stacked 2',
                        data: [56, 30, 0, 0, 0, 36, 70],
                        labels: {
                            font: '12px sans-serif'
                        }
                    },
                    {
                        type: 'stacked100Area',
                        title: 'Stacked 3',
                        data: [33, 42, 54, 23, 54, 47, 61],
                        labels: {
                            font: '12px sans-serif'
                        }
                    }
                ]
            });
        });
    </script>

</head>
<body>
    <div>
        <div id="jqChart" style="width: 500px; height: 300px;"></div>
    </div>
</body>
</html>


Description of Bug
You'll notice that rather than allowing the series with data to dominate the chart, the series with values of 0 do not disappear; rather, those series with values of 0 "extend" (overlap) the series with data, visually indicating the presence of greater than 0 data.

I'd post a picture; however, I am having great difficulty getting a picture from my file system into your forum
