title: JFreeChart Stacked Area Chart not continous
body: <p>I used the <a href="http://www.jfree.org/jfreechart/api/javadoc/org/jfree/chart/ChartFactory.html#createStackedAreaChart%28java.lang.String,%20java.lang.String,%20java.lang.String,%20org.jfree.data.category.CategoryDataset,%20org.jfree.chart.plot.PlotOrientation,%20boolean,%20boolean,%20boolean%29" rel="nofollow"><code>createStackedAreaChart()</code></a>, but the stacked area chart I got is not continous. There are gaps between categories (just look like stacked bar chart). But If I use <code>createAreaChart()</code> for the same dataset (<code>DefaultCategoryDataset</code>), the area chart is fine. What's wrong with the stacked area chart? I would really appreciate any help. </p>
