If getting data from the web api, make sure the web api is configured. Version 19.1.1 or later releases are currently the only versions supporting this functionality. See:
In the following example is a call made to the web api and how to import it to power BI.
The first part of the call is specifying machine name and the port to access the web api service. The gettagdata is using a get call to get tags from data view localhost. The data set is Data Generation. The tag name is Decay 0001. The & is also asking for data from a start time of month (beginning of the month) to an end time of now. More information about calls and terms can be found in the web api help.
Once the call returns in the web api, it can also be made from the Power BI app. To accomplish this:
- Open the Power BI app an click Get data
- Click other, web, and connect. This will promt for a url.
- Next insert the web api url call.
- After pressing the OK button, an image like this should appear.
- Clicking on data records will give a path with a list beside it.
- Now it is possible to make it to a table by clicking the upper left hand button selecting any delimeters and pressing OK.
You can also edit it after the fact in the query editer
- In this example we will split the timestamp and value by using the query editor by clicking on the split arrow.
- Then split the timestamp column to extract the time from the date.
- Column t.3 is of no use and will be deleted. The other columns are renamed. After editing is completed close and apply changes.
- Once the data has been uploaded to the visual tool it is ready to be used in layouts.
