如何在amCharts股票图表中使用多个数据集？

Question

I have two datasets and want to use them to display the line charts in amCharts Stock Chart. This is the fiddle. It only shows the data from the first dataset.

 "stockGraphs": [ 
    {
      "id": "g1",
      "title": "Graph #1",
      "lineThickness": 2,
      "valueField": "value1",
      "useDataSetColors": false,
      "valueAxis" : "axis1",


    }, 

    {
      "id": "g2",
      "title": "Graph #2",
      "lineThickness": 5,
      "valueField": "value2",
      "useDataSetColors": false,
      "connect" : false,
       "valueAxis" : "axis2"

    }

I am sure there is a simple JSON config missing somewhere. Can someone please help me with this?

There are a few things that need to be done in order to display graphs from the compared data sets.

1) Make the second data set compared by setting compared: true .

2) Set comparable: true and compareField for the second graph.

3) Your fiddle code creates data for the second data set with "value1" as a value field, while graph valueField refers to "value2".

Here's your chart with all of the above applied:
