   As you already figured out, _graph_ series **cannot** get their data from _datasets_ .  _Line_ series can, because they have the [datasetIndex](https://echarts.apache.org/en/option.html#series-line.datasetIndex) attribute, graphs do not (and I doubt this is a good feature candidate).
   
   Graphs need a **data source pair** - [nodes](https://echarts.apache.org/en/option.html#series-graph.nodes) and [links](https://echarts.apache.org/en/option.html#series-graph.links).
   Try updating _series[0].nodes_ and _series[0].links_  in myChart.setOption() ? It should work.
