java - 在StackedXYAreaChart中禁用系列-jfreechart

我正在尝试创建一个用户过滤器，该过滤器将基于用户单击来启用/禁用一系列操作。我添加了一个复选框按钮，它将启用/禁用该系列。

当我单击按钮时，只有图例项消失。图上的区域仍然可见。我的方法错了吗？还是在StackedXYAreaChart中不可能？我究竟做错了什么 ？

最佳答案

该问题在StackedXYBarRenderer中描述为here。

最简单的解决方案是覆盖默认渲染器的drawItem()方法以增强可见性：

public void drawItem(Graphics2D g2,
                     XYItemRendererState state,
                     Rectangle2D dataArea,
                     PlotRenderingInfo info,
                     XYPlot plot,
                     ValueAxis domainAxis,
                     ValueAxis rangeAxis,
                     XYDataset dataset,
                     int series,
                     int item,
                     CrosshairState crosshairState,
                     int pass) {
    if (!getItemVisible(series, item)) {
        return;
    }
    super.drawItem(g2, state, dataArea, info, plot, domainAxis, rangeAxis, dataset, series, item, crosshairState, pass);
}

但是，输出可能不是预期的：
