series method

Future<List<CubeSeries>> series(String cube, List<String> xAxis, { List<String>? series, List<String>? indices, Map<String, dynamic>? filters, bool? groupIndices, bool? inverseIndices, })

Retrieve series of cube by xAxis. If series are set, each CubeSeries.name receive the series group value. If indices are set, each CubeSeries.index is set to the index name.
