Node-RED系列文章目前已经写了18篇，介绍了Node-RED的安装以及默认安装的一些基本节点的使用，作为物联网的一个可视化拖动的流程,Node-RED的确实很容易上手。还没开始学习的同学可以先看下我以前的文章。

效果图
首先来看一下效果图，
改仪表盘，使用多个数据源，并通过一些function节点，将数据封装处理后，输入到折线图，柱状图，饼图，以及雷达图上。 该方案可以在一个页面，制作多组数据图表。方便用户筛选，查看。
实现方案
安装dashboard节点 用于tab，group布局，chart节点用于承载图表 安装random节点，用于生成随机数用到的图表有这几个
line chart 折线图 bar chart 柱状图 bar chart （H） 横向柱状图 pie chart 饼图 polar area chart 极地坐标图 radar chart 雷达图使用注入节点来配置数据，如label， data， 使用function 节点来处理数据 如
var m={}; m.labels = [“January”, “February”, “March”, “April”, “May”, “June”, “July”]; m.series = [Series A, Series B, Series C]; m.data = [ [65, 59, 80, 81, 56, 55, 40], [28, 48, 40, 19, 86, 27, 90], [38, 28, 20, 49, 45, 60, 20] ]; return {payload:[m]}; 折线图配置
雷达图
分析数据流转
以一源对多表1的示例来讲解一下数据的流转
该图显示如下，
一共是四个图，四个图使用同一份数据源
数据源使用function节点来生成,内容如下
可以简单理解为这样。 一共有三个维度。
labels 对应的是x轴的值 data 中的数据 对应的是y轴的值 series 对应的是系列，分类如 一源对多表5的数据如下
var m={ “series”:[“X”,”Y”,”Z”], “data”:[[5,6,9],[3,8,5],[6,7,2]], “labels”:[“Jan”,”Feb”,”Mar”] }; return {payload:[m]};只有三个维度，series，data , labels
