        Ok, for a start, that's just a single number. It's not a javascript object so you can't use that dotted object notation.
        Let's look at the raw data coming from the serials values, if it's anything like this:
        [ {timestamp:1539247293,value:3}] the approach will have to be changed.

        Do not follow where the path may lead; go instead where there is no path.

          Yep, I think you need to look at changing your format. You need the timestamps as your values.
          You also need to establish what your start and end times are per each serial. The timestamp by itself won't be enough unless you know you can comfortably add an additional hour for the to attribute or subtract for the from attribute...

            the timestamp would be from Serial number to Serial Number+1

              Then what do you do when you use the latest serial number? Go from that timestamp to now?

                  @ronnyhinkel said in Dropdown selection for datapoint values:

                  ng-change="callOnChange()"

                  ng-change="callOnChange()"
                  Are you writing your own controller?

                      Ok, I'm gonna be clever...

                      <md-select ng-model="serialID" ng-required="true" >
                      <md-option ng-repeat="(index,serial) in serials" ng-value="index" > {{serial.value}} </md-option>
                      </md-select>
                      
                      <div ng-if="serialID==(serials.length-1)">
                      <ma-now update-interval="15 MINUTES" output="time"></ma-now>
                      <ma-point-values point-xid="DP_bf4e8b98-ff25-439c-a63e-4af21bc92902" point="point1" values="point1Values" from="serials[serialID].timestamp" to="time" ></ma-point-values>
                      </div>
                      
                      <div ng-if="serialID<(serials.length-1)">
                      <ma-point-values point-xid="DP_bf4e8b98-ff25-439c-a63e-4af21bc92902" point="point1" values="point1Values" from="serials[serialID].timestamp" to="serials[(serialID+1)].timestamp" ></ma-point-values>
                      
                      </div>
                      

                      Using Ng-if will create these elements provided one of the if statements are met. Using the index allows us to make this list grow wholly depending on the number of your serials. If you're on the last serial, it sees we're using the last index and thus uses a ma-now directive to give us the browser time from the serial creation time!

                          You're welcome, sorry for the lack of comments. Let me know if there's anything you don't understand after comparing it with the angularJS docs
