good morning to all,

I am trying to make a HeatMap like this [Ignition Exchange | Inductive Automation](https://inductiveautomation.com/exchange/2127/overview)  
but in my case I need one for Vision...

Is there an example similar to this one? or is there any other alternative to do it?

Exactly I would need to monitor the temperature of 14 racks for 24 batteries in a matrix like this one

I don't have one made, but it wouldn't be super difficult using a template and the template repeater component in Vision.

I'd go straight to the paintable canvas and just paint lots of rectangles.

that's exactly what I did hehe, I took a matrix and assigned the temp value to each one and then with an expression in the backgroundcolor I indicated that if it is greater than 75º it changes color....

I thought there was a horseshoe but it turned out to be simpler than I expected,  
thanks again Phil
