i want to read and display measuring data with dashboard nodes.
How is it possible to read a table with already measured values (.csv or .txt) and use the gauge and chart function to simulate that the sensordata is appearing for example like every second.
When I try to read a table I only get the whole information and the gauge and chart function don´t work.
The gauge needs the infomation piece by piece. Ich want the content of each row of the table to be displayed with the gauge or chart every second.
Structure of the table:
sensor a; sensorvalue a; sensor b; sensorvalue b
I hope for some example flows to solve the problem.
Thank you for help.
