achartengine泡沫图泛问题

我在achartengine中有一个气泡图。我有XYMultipleSeriesRenderer，我添加了XYValueSeries，并绘制了几个点。我有X轴和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。所以我做的是设置setXAxisMax(10)和setYAxisMax(10)，以便在轴上一次显示10个点。但是，如果您平移并移动应用程序崩溃，则例外：

请让我知道可能是什么问题

1 个答案:

答案 0 :(得分：2)

这是我自己的代码的问题。 X值需要以递增方式添加到XYValueSeries，即如果添加5，则以后不能再添加4等X值。所以我解析JSON然后根据X值对集合进行排序，然后按顺序将它们添加到系列中。
