Hi @leoeinsfeld ,

1st Create a Thing in ThingWorx and bind PLC tags as a properties in Thing.

For showing the Tags value in chart, it is necessary to store the properties in stream or value stream.

In Mashup, you have to call the following services.

1. for stream - QueryStreamEntriesWithData

 2. for Value Stream - QueryPropertyHistory

Bind the data of service to chart widget.

In chart widget properties, select PLC Tags for X and Y axis label.

Also bind auto refresh widget to service so when values are changed in PLC it will reflect in chart.
