Hello to all,
"I have created a Canvas panel and intend to use it as a simple SCADA/HMI application for visualization. The project is inspired by similar wind turbine and solar panel examples.
However, my application is slightly more complex because I collect both real-valued and binary data from a datalogger. The binary signals indicate whether a valve/flap is open or closed, or if a pump is on/off.
I’m not entirely sure how to implement this. I have already set a static image as the canvas background. In previous applications, I would stack two images and toggle their visibility based on the binary signal, but I’m not sure if that approach works in Grafana.
Could you suggest a way to achieve this using the Canvas panel?
I’m open to alternative approaches if this is not possible. One other idea that comes to my mind is to use a rectangle with boundary colored if the flap is open.
Thank you!
