我有一个气泡图achartengine。我有一个XYMultipleSeriesRenderer，我添加了一个XYValueSeries并绘制了几个点。我有 X 和 Y 轴的自定义标签。问题是当我们将所有点一起显示时标签太小了。所以我所做的就是设置setXAxisMax(10)，setYAxisMax(10)以便在轴上一次显示 10 个点。但是，如果您平移和移动应用程序崩溃，但以下情况除外：

这是我自己的代码的问题。X 值需要以增量方式添加到 XYValueSeries 中，即如果添加 5，则以后无法添加 X 值 4 等。因此，我解析 JSON，然后根据 X 值对集合进行排序，然后按该顺序将它们添加到系列中。
