问题描述
我有一个JFree条形图。则使用DefaultCategoryDataset,
填充数据集。可能存在域和范围轴上的值使得这些值不是非常清晰可见的情况。
I have a JFree Bar Chart. the dataset is populated using DefaultCategoryDataset ,There may be situations when the values on both the domain and range axis are such that these values are not very clearly visible.
我需要一个像scrollPane这样的图表可以添加。但它看起来像ChartPanel不能添加到JScrollPane
I need something like a scrollPane into which the chart can be added. But it looks like the ChartPanel cannot be added into a JScrollPane
有任何方法这样做吗?
