 ### Multiple time series
 A time series is a set of data points that are ordered by time for a given combination of dimensions. A dimension is an aspect of the metric that describes the data point such as resource Id, region, or ApiName. 
-+ To fetch multiple time series with specific dimension values, specify a filter query parameter that specifies both dimension values such as `"&$filter=ApiName eq 'ListContainers' or ApiName eq 'GetBlobServiceProperties'"`.  In this example  you get a time series where `ApiName` is  `ListContainers` and a second time series where `ApiName` is `GetBlobServiceProperties`.
-+ To return a time series for every value of a given dimension, use an `*` filter such as `"&$filter=ApiName eq '*'"`. Use the `Top` and `OrderBy` query parameters to limit and sort the number of time series returned.  In this example you get a time series for every value of `ApiName`in the result set. IF no data is retured, the API returns an empty time series `"timeseries": []`.
