href="https://summer.iscas.ac.cn/#/homepage" target="_blank">开源软件供应链点亮计划</a>鼓励大家关注开源软件和开源社区，致力于培养和发掘更多优秀的开发者。我们鼓励研究人员、开源爱好者、在校师生参与开源软件的开发与维护，促进开源软件的发展和优秀开源软件社区建设，增加开源项目的活跃度，推进开源生态的发展。</p><p>主办方会资助最终有学生申请的项目，根据难度不同，对应税前奖金分别为高（12000 元）、中（9000 元）、低（6000 元）（注：奖金数额为税前人民币金额），具体请参考开源软件供应链点亮计划官方说明。</p><p>社区针对每个项目需要指定一名社区导师，在这一过程中，可以在导师的帮助下对 Apache ECharts 项目开发有更好的了解。</p><h3>活动报名</h3><p>请前往<a href="https://summer.iscas.ac.cn/help/student/" target="_blank">活动官网</a>报名或了解更多信息。</p><h3>项目列表</h3><p>申请者可以在以下列表中选一个项目完成：</p><table><tr><th>序号</th><th>名称</th><th>难度</th><th style="width: 40%">描述</th><th>产出</th><th>要求</th></tr><tr><td>#1</td><td>关系图支持拖动数据点</td><td>低</td><td>支持关系图 layout: none 情况下的数据点拖动功能。相关 issue：<a href="https://github.com/apache/echarts/issues/14510" target="_blank">#14510</a></td><td>实现关系图 layout: none 情况下的数据点拖动功能</td><td>TypeScript</td></tr><tr><td>#2</td><td>关系图可配置是否自动缩放成视图大小</td><td>低</td><td>在 layout: none 布局下，允许开发者通过配置项关闭节点位置的调整，保证开发者给定的位置即为最终渲染的坐标。相关 issue：<a href="https://github.com/apache/echarts/issues/13516" target="_blank">#13516</a></td><td>添加一个配置项，开启后可以实现坐标轴标签的交替显示</td><td>TypeScript</td></tr><tr><td>#3</td><td>Apache ECharts Issue Helper</td><td>中</td><td><a href="https://github.com/ecomfe/echarts-issue-helper" target="_blank">Apache ECharts Issue Helper</a> 是用来生成 GitHub Issue 的表单工具，通过表单而非 Markdown 的形式能更好地确保提问者给出必要的信息。但是目前功能比较有限，希望增强 Markdown 相关功能</td><td><ol><li>支持 Markdown 格式（含代码）高亮</li><li>支持上传图片</li><li>支持 Markdown 结果预览</li></ol></td><td>TypeScript；Vue.js（可以现学）</td></tr><tr><td>#4</td><td>官网示例支持第三方编辑器</td><td>中</td><td>Apache ECharts 官方网站示例部分目前使用自有的代码编辑器，社区希望同样提供在主要第三方在线编辑器（StackBiz、 JSFiddle、 CodePen、 CodeSandbox）中编辑示例的功能</td><td><ol><li>在Apache ECharts 官网示例组件中添加 ”前往 CodeSandbox / StackBlitz / jsfiddle / CodePen 编辑“的按钮</li><li>调用第三方在线编辑器的 API，在跳转时将该示例所使用的代码传入</li></ol></td><td>JavaScript</td></tr><tr><td>#5</td><td>河流图的非对称绘制</td><td>中</td><td>Apache ECharts 的河流图目前使用对称绘制的方法进行绘制（整体图案沿 x 轴对称），希望通过 wiggle 算法实现非对称的绘制以增加河流图的可观性。相关 issue：<a href="https://github.com/apache/echarts/issues/14643" target="_blank">#14643</a></td><td>添加一个配置项，开启后可以实现坐标轴标签的交替显示</td><td>TypeScript；对图形学有简单了解（需要阅读算法论文并实现）</td></tr><tr><td>#6</td><td>扩展标签的防重叠</td><td>高</td><td>Apache ECharts 现在在饼图等某些特定的图上提供了标签的防重叠布局算法。现在希望能够增加一个更加通用的布局算法，通过迭代搜寻标签可以放置的位置，寻找一个较优的位置，解决散点图等图中数据量比较多的时候的标签重叠问题。可以参考已有的论文和实现：1. An Empirical Study of Algorithms for Point-Feature Label Placement 2. <a href="https://github.com/tinker10/D3-Labeler" target="_blank">https://github.com/tinker10/D3-Labeler</a> 3. <a href="https://cran.r-project.org/web/packages/ggrepel/vignettes/ggrepel.html" target="_blank">https://cran.r-project.org/web/packages/ggrepel/vignettes/ggrepel.html</a></td><td><ol><li>添加一个配置项，开启后可以实现标签的只能防重叠</li><li>防重叠的算法能够做到性能，实现复杂度（代码量）和最终效果之间的平衡</li></ol></td><td>TypeScript</td></tr><tr><td>#7</td><td>坐标轴标签实现交错显示从而优化标签的重叠问题</td><td>高</td><td>现在 Apache ECharts 的坐标轴在标签过多的时候只能做到隐藏部分会重叠的标签，但是某些场景下可以做到标签的上下交错显示而不用隐藏，现在希望能够添加一个配置，用户开启后可以智能得把重叠的标签往上/下移（如果是 Y 轴则是左/右）</td><td>加一个配置项，开启后可以实现坐标轴标签的交替显示</td><td>TypeScript；需要阅读算法论文并实现</td></tr><tr><td>#8</td><td>关系图节点自身的循环引用</td><td>高</td><td>关系图节点可以指向自己，目前尚未支持这一功能。相关 issue：<a href="https://github.com/apache/echarts/issues/12951" target="_blank">#12951</a></td><td><ol><li>关系图节点可以指向自己</li><li>可以配置参数控制连线位置</li><li>支持多条指向自己的连线</li></ol></td><td>TypeScript</td></tr></table><h3>寻求帮助</h3><p>如果有活动形式相关的问题，请咨询<a href="https://summer.iscas.ac.cn/help/contactus/">活动主办方</a>。如有和项目相关的问题，可以在 Apache ECharts <a href="mailto:dev@echarts.apache.org">邮件列表</a>中和我们交流。</p></div></div><footer><div class="container"><div class="row"><div class="col-md-9"><p>Copyright © 2017-2021, The Apache Software Foundation Apache ECharts, ECharts, Apache, the Apache feather, and the Apache ECharts project logo are either registered trademarks or trademarks of the Apache Software Foundation.</p><div class="icon-panel"><a href="mailto:dev@echarts.apache.org?body=%28Thanks%20for%20using%20ECharts.%20Email%20us%20if%20you%20have%20non-technical%20problems%20using%20ECharts.%20For%20technical%20support%2C%20please%20go%20to%20https%3A//github.com/apache/echarts/issues%20.%29" class="footer-icon"><img src="https://cdn.jsdelivr.net/gh/apache/echarts-website@asf-site/zh/images/icon-email.png?_v_=20200710_1"></a><a href="https://twitter.com/ApacheECharts" class="footer-icon"><img src="https://cdn.jsdelivr.net/gh/apache/echarts-website@asf-site/zh/images/icon-twitter.png?_v_=20200710_1"></a><a href="https://weibo.com/echarts" class="footer-icon"><img src="https://cdn.jsdelivr.net/gh/apache/echarts-website@asf-site/zh/images/icon-weibo.png?_v_=20200710_1"></a><a href="https://github.com/apache/echarts" class="footer-icon"><img src="https://cdn.jsdelivr.net/gh/apache/echarts-website@asf-site/zh/images/icon-github.png?_v_=20200710_1"></a></div></div><div id="footer-icon-panel" class="col-md-3"><a href="https://www.apache.org"><img src="https://cdn.jsdelivr.net/gh/apache/echarts-website@asf-site/zh/images/asf_logo.svg?_v_=20200710_1" class="footer-apache-logo"></a></div></div></div></footer></div></div><script type="text/javascript" src="https://cdn.jsdelivr.net/npm/bootstrap@3.3.7/dist/js/bootstrap.min.js"></script><script type="text/javascript" src="https://cdn.jsdelivr.net/gh/apache/echarts-website@asf-site/zh/js/common.js?_v_=b5b8944fb9"></script><script>window.lazyLoadOptions = {
