Hist4j 介绍
Hist4j是一个开源的绘制柱状图的Java类库，支持大数据量的现实。
Features
- It adapts to any data distribution, keeping a more or less constant resolution throughout the data range by increasing the resolution where the data is more dense.
- It can process large amounts of data with a very small memory footprint.
- It doesn’t need pre- or post-processing to deliver statistics about the data seen so far.
