Graph Appearance Issue

[TaufeeyTonello]

Dear All, 

Hoping you are doing good, please attachment code of PID implementation for UP55A Temperature Controller & image, the thermocouple should give the smooth graph on the roll-off decay but it shows noise I could not the problem why it's appearing like this, guidance needed. Thanks in advance.

Hi Taufeey,

please attachment code of PID implementation for UP55A Temperature Controller & image,

I don't see any "PID implementation" in your VI or image.

All you do is to read some parameters from your external temp controller using Modbus communication.

the thermocouple should give the smooth graph on the roll-off decay but it shows noise

Where do you see noise? In your image the plots show "nice" noise-free data.

There also is no graph in your VI

Dear GerdW, 

The Green line shows some jittering it should be smooth that I wanna know how I can make it smooth. I took several attempts but couldnt achieve the desired waveform.

Hi Taufeey,

The Green line shows some jittering it should be smooth that I wanna know how I can make it smooth.

It looks smooth to me - in this screenshot…

I took several attempts but couldnt achieve the desired waveform.

Which attempts did you take?

Can you attach a VI showing your attempt, with some typical sensor data as default data?

What about a RunningAverage function to smooth the data (aka lowpass filtering)?
