DataEase 自定义图表开发全流程指南从架构设计到生产部署【免费下载链接】dataease 人人可用的开源 BI 工具数据可视化神器。An open-source BI tool alternative to Tableau.项目地址: https://gitcode.com/GitHub_Trending/da/dataeaseDataEase 作为开源 BI 工具其自定义图表开发能力为开发者提供了强大的数据可视化扩展机制。本文深入解析 DataEase 图表插件架构通过完整的实战示例帮助开发者掌握从零构建自定义图表的完整流程。核心关键词DataEase 自定义图表开发。长尾关键词图表插件架构设计、ECharts 集成方案、AntV G2Plot 扩展、图表性能优化策略。架构设计与核心原理DataEase 采用插件化架构设计通过统一的接口规范实现图表引擎的可扩展性。图表插件体系的核心位于 sdk/extensions/extensions-view/ 目录该模块定义了图表插件的完整生命周期管理机制。插件架构分层模型DataEase 的图表插件架构采用三层设计基础抽象层、插件实现层和工厂管理层。基础抽象层由AbstractChartPlugin定义该抽象类规定了图表开发的四个核心生命周期方法public abstract class AbstractChartPlugin { // 处理坐标轴字段配置 public abstract T extends AxisFormatResult T formatAxis(ChartViewDTO view); // 处理过滤条件和交互逻辑 public abstract T extends CustomFilterResult T customFilter( ChartViewDTO view, ListChartExtFilterDTO filterList, AxisFormatResult formatResult); // 计算图表数据结果 public abstract T extends ChartCalcDataResult T calcChartResult( ChartViewDTO view, AxisFormatResult formatResult, CustomFilterResult filterResult, MapString, Object sqlMap, SQLMeta sqlMeta, Provider provider); // 构建最终图表配置 public abstract T extends ChartViewDTO T buildChart( ChartViewDTO view, ChartCalcDataResult calcResult, AxisFormatResult formatResult, CustomFilterResult filterResult); }插件注册与发现机制图表插件的注册通过PluginsChartFactory实现该工厂类采用双重注册机制静态注册和动态加载。每个图表插件需要继承DataEaseChartPlugin并实现loadPlugin()方法public abstract class DataEaseChartPlugin extends AbstractChartPlugin implements DataEasePlugin { Override public void loadPlugin() { XpackPluginsViewVO viewConfig getConfig(); PluginsChartFactory.loadPlugin( viewConfig.getRender(), viewConfig.getChartValue(), this ); } public abstract XpackPluginsViewVO getConfig(); }图1DataEase 基础柱状图示例展示插件架构处理的数据可视化效果开发环境与工具链配置环境搭建与依赖管理DataEase 采用 Maven 作为后端构建工具前端使用 Vue 3 TypeScript。开发自定义图表需要配置完整的开发环境# 克隆项目仓库 git clone https://gitcode.com/GitHub_Trending/da/dataease.git cd dataease # 安装前端依赖 cd core/core-frontend npm install # 编译后端扩展模块 cd sdk/extensions/extensions-view mvn clean compile -DskipTests开发调试环境配置后端开发环境需要启动 Spring Boot 应用建议使用开发模式cd core/core-backend mvn spring-boot:run -Dspring-boot.run.profilesdev前端开发环境启动命令cd core/core-frontend npm run dev核心模块实现详解ECharts 图表插件实现ECharts 作为 DataEase 支持的主要图表引擎之一其插件实现需要处理数据格式转换和渲染配置生成。以下是 ECharts 柱状图插件的核心实现public class EChartsBarPlugin extends DataEaseChartPlugin { Override public AxisFormatResult formatAxis(ChartViewDTO view) { // 处理坐标轴配置 AxisFormatResult result new AxisFormatResult(); ListChartViewFieldDTO xAxis view.getXAxis(); ListChartViewFieldDTO yAxis view.getYAxis(); // 标准化坐标轴字段 result.setxAxis(standardizeAxisFields(xAxis)); result.setyAxis(standardizeAxisFields(yAxis)); return result; } Override public ChartCalcDataResult calcChartResult(ChartViewDTO view, AxisFormatResult formatResult, CustomFilterResult filterResult, MapString, Object sqlMap, SQLMeta sqlMeta, Provider provider) { // 使用 ChartDataUtil 进行数据转换 ChartCalcDataResult result new ChartCalcDataResult(); ListString[] rawData executeQuery(sqlMap, sqlMeta, provider); // 数据排序和格式化 ListString[] sortedData ChartDataUtil.resultCustomSort( formatResult.getxAxis(), formatResult.getyAxis(), view.getSortPriority(), rawData ); result.setSeriesData(sortedData); return result; } Override public ChartViewDTO buildChart(ChartViewDTO view, ChartCalcDataResult calcResult, AxisFormatResult formatResult, CustomFilterResult filterResult) { // 构建 ECharts 配置选项 MapString, Object echartsOption new HashMap(); // 配置坐标轴 echartsOption.put(xAxis, buildEChartsXAxis(formatResult.getxAxis())); echartsOption.put(yAxis, buildEChartsYAxis(formatResult.getyAxis())); // 配置数据系列 ListMapString, Object series convertToEChartsSeries( calcResult.getSeriesData(), formatResult ); echartsOption.put(series, series); // 应用样式配置 applyStyleConfig(echartsOption, view.getStyleConfig()); // 设置图表配置到视图 view.setChartConfig(JSON.toJSONString(echartsOption)); return view; } }数据格式转换工具DataEase 提供了ChartDataUtil和FieldUtil工具类简化数据格式转换过程public class DataConverterUtil { public static MapString, Object convertToEChartsFormat( ListChartViewFieldDTO xAxis, ListChartViewFieldDTO yAxis, ListString[] seriesData) { MapString, Object result new HashMap(); // 构建 X 轴数据 ListString xAxisData new ArrayList(); for (String[] row : seriesData) { xAxisData.add(FieldUtil.formatValue(xAxis.get(0), row[0], null)); } result.put(xAxisData, xAxisData); // 构建系列数据 ListMapString, Object seriesList new ArrayList(); for (int i 0; i yAxis.size(); i) { MapString, Object series new HashMap(); series.put(name, yAxis.get(i).getName()); ListObject data new ArrayList(); for (String[] row : seriesData) { data.add(FieldUtil.formatValue(yAxis.get(i), row[i 1], null)); } series.put(data, data); seriesList.add(series); } result.put(series, seriesList); return result; } }图2DataEase 多图表组合大屏展示复杂业务场景下的数据整合能力AntV G2Plot 集成方案G2Plot 图表适配器AntV G2Plot 作为另一个主流的可视化引擎其集成方案需要实现特定的适配器接口public class G2PlotChartPlugin extends DataEaseChartPlugin { private static final String RENDER_TYPE antv;
