Device graph data

Hi Team,

I used the below link to get graph data for the device (Single Instance) .

https://www.logicmonitor.com/support/rest-api-developers-guide/v1/data/get-graph-data/

Here I used the below Rest API 

/device/devices/{deviceID}/devicedatasources/{deviceDataSourceID}/instances/{instanceID}/graphs/{graphID}/data

Here I have provided all input parameters for this URI.

But I didn't get any data for it. I was getting only "No Data" for it . But that server acutally has data .

outPut:

 

"data" : [ "No Data", "No Data", "No Data", "No Data", "No Data", "No Data", "No Data", "No Data", "No Data", "No Data", "No Data", "No Data", "No Data", "No Data" ]
