java - AFreeChart OHLC 数据集 : how to remove spaces where no data at date axis?

Question

3月9日-10日没有数据，请问这段时间可以去掉空格吗？

Answer 1

如果是周末数据产生了差距，你可以这样做

SegmentedTimeline timeline = SegmentedTimeline.newMondayThroughFridayTimeline();
((DateAxis) chart.getXYPlot().getDomainAxis()).setTimeline(timeline);

或

final OHLCDataset dataset = new DefaultOHLCDataset("Series1", ohlc);
SegmentedTimeline timeline = SegmentedTimeline.newMondayThroughFridayTimeline();
chart = ChartFactory.createHighLowChart(this.getTitle(),xLabel, yLabel,dataset,timeline, false);

如果不是周末，那么您将不得不更聪明地使用 SegmentedTimeline api
