Dashboard,即商业智能仪表盘,主要用于呈现数据可视化效果。它可以帮助用户以图表、图形和表格的形式展示数据,并允许用户自定义和个性化仪表盘,以适应不同的数据可视化和可视设计需求。通过仪表盘,用户可以更快速地访问和理解数据,从而更好地进行决策和管理。
ECharts中制作Dashboard仪表盘也很简单,只需将之前介绍的ECharts组件以及图表根据需要进行组合即可。

本次将实现一个反映电商平台销售情况的Dashboard仪表盘,可视化效果如下所示(数据仅为示意):

可以通过以下步骤实现上述图表:

  • 所有文字都在标题组件中,文字的位置通过lefttop来控制文字距离容器左侧和上侧的距离,并通过textStyle来设置文字的大小和颜色;

  • 通过center设置饼图的中心(圆心)坐标,通过radius设置饼图的半径,通过字符串模板formatter设置饼图的文本标签;

  • 下方的条形图和折线图的位置通过grid网格来设定,通过left、right、top、bottom来设定图表所占的空间大小,需要注意的是gridindex要与x、y轴相对应,series中的数据系列要与xAxisIndex、yAxisIndex对应

完整代码如下所示:
