Disclaimer: Microsoft is working hard to integrate Data Connectors to the Office Store. Until they do, please complete the following steps:
Create a [My Documents]\Microsoft Power BI Desktop\Custom Connectors directory.
Download Patternchain extension here and place it into the above-created directory.
Enable the Custom data connectors preview feature in Power BI Desktop (under File | Options and settings | Options | Preview Features | Custom data connectors).
Restart Power BI Desktop and click "Get Data". Select Patternchain (Beta) and click "Connect".
Enter any amount just to load a hundred rows and click on "Edit Queries". From there, click on "Advanced Editor"
Comment / Uncomment any of the Patternchain functions, change values as desired, and click "ok"
Voilà! Using Power Query (aka Language M), you have combined three Patternchain functions into a single table.
** Should you have any issues connecting to Patternchain, don't hesitate to contact us.
