国外开源报表工具和国产商用报表工具有什么不同?

报表工具关于开源还是商用的争论一直没有消停过,其实不管两者存在哪些差异,都应该不忘初心、按需选择。正因为需求不同,选择也不一样,所以在做出选择之前,要先搞清楚自己的需求是什么,然后再去做有针对性的对比,这样更有意义。 关于两个有什么不同 简单列出如下几点: 1、 开发模式不同 国外开源报表工具编辑器大多是拖拽控件式的较国内商用报表工具类 excel 的编辑器 兼容性差,不易上手 2、 国外开源报表工具很难搞定中国式复杂报表,比如:多源分片报表 3、 国外开源报表缺失数据填报录入功能 等… 详情可参考如下文章 开源报表和商用报表哪个好用? 总结: 国外开源报表: 优点:免费 缺点:功能不全、学习成本高、没有技术支持… 商用报表优点:提供了所有开源报表不支持或者压根就没有的功能; 缺点:价格比较昂贵。 润乾报表不仅兼具了两者的优点,功能非常完善,价格也很低廉,总体拥有成本比开源产品还低。 另附上一些报表工具选型对比的文章作为参考: 【java 报表工具报表软件选型经验总结分享】 https://blog.csdn.net/RQlyc/article/details/83750523 【报表工具对比之润乾报表与 JFreeReport】 https://blog.csdn.net/rqgxy/article/details/85786053 来源: oschina 链接: https:/

This is what I have today My values are {2, 2, 1.5} By default max value is set to the max value of my dataset (here 2) but I want to set it to 5 which as you can see it did but it did not draw the lines for the value between 2 and 5. How can I progamatically draw them ? UPDATE AFTER COMMENT : SpiderWebPlot plot = (SpiderWebPlot)chart.getPlot(); plot.setMaxValue(5.00); plot.setHeadPercent(0.01); return chart; I am using JFreeChart
