I have a device that receives information from a sensor. The sensor information is displayed on a graph. At certain points on this device, the variable becomes negative and resets to zero. How can I exclude this negative and reset variable from the graphs so that it doesn't apply to the invoice, since it makes no difference and will end up interfering with Excel exports?

I believe that you can set the range in the tag to solve this.

Yes, it works, the problem is that I don't want the value to appear. For example, in the scale, I select (1 to 99%). Therefore, the minimum value will be 1, but I don't want that value to appear.

I would like it to hide when it reaches the minimum set value. How do I proceed?

The best way to handle this might be to create a calculation tag which references the measured I/O and stores the modified data using a calculation.

For example, a simple ternary should handle this

[MyTag] > 1 ? [MyTag] : INVALID

note I haven't tested that code but in theory that would work.

I think it worked...if it's less than 5, it appears as invalid...and if it's greater than 5, the value appears...however, how do I remove the "?" when the value appears? So it doesn't end up as "16?"

Is there also the possibility that this question "?" when it is less than 5, presents a text? Example: "Erando". It is a piece of equipment in the chemical area. @ArghDave

Oh, yes, I understand. But how do I make it display a word when it's less than 5? Without using the Questionable Flag?

I ran a test here. It's working in the calculation, the word appears when it's below 5, but it doesn't appear in the GRID plot. Does anyone know how to fix it?
