Json Multilevel in couchDB

CouchDB provide responses with this header '{"total_rows":25,"offset":0,"rows":[' and the table is not plotting, can anyone help ?

I've changed server.data-source.ts to

> ServerDataSource.prototype.extractDataFromResponse = function (res) {
> var rawData = res.json()**.rows;**

But the table is plotting with correct rows number, but only one big cell empty
