Reference in waveform chart

[lizandra]

hi everyone!

im having some problems with my code. i cant put a reference line (or another function, like a reference sinusoid) in waveform chart, i tried putting a bundle, but i couldnt get it to work, the bundle does not wire in the waveform chart. i'd like the references to stay still and not move like in the picture.

the other thing is that im working with force control, and i want to save in an array 3 max force values (there will be 3 tasks of maximum force, and i want to save the 3 max values with 60s interval in between them, running the program only once), but it is not working.

some ideas, please? 🙂

To write multiple plots to your chart, you need an array of waveforms.  One waveform will be your reference.  You can make another for each of your max values.

hi! thanks for the answer!

i did this

but it is still not working 😞 what should i do? i dont know what to wire in the Y in the build waveform.

I was thinking something more like this:

i did what you said, and it almost worked the way i wanted (but im getting close, so thank you so much)

this is what im seeing

the reference is following the signal, and i wanted the reference to be there already, like this

any idea?

Weill I did have an idea to just use two data points and a large "dt" and then presenting an empty Y array for the reference line ....

but...

The chart is misbehaving and time is running in reverse, dogs and cats living together...

It can be done using graph that is populateed with "NaN" for the "yet to be acquired" but before you go to that work and have to reinvent the chart...

Consider the benefits of what crosrulz showed you. Using that approach the refernce line can change "on the fly" which is a very desireable thng.
