Programatically stack plots on a waveform graph

[ritch_by_nature]

Has anyone been able to solve this mystery? Please help.

I guess that I am not completely sure what you are looking to do? Do you want multipule plots on a single graph or do you want stacked graphs that display data for one curve? You should be able to do either of these but it would be helpful to understand what you are looking to do.

I can do multiple plots on a graph, but I want to do a stack where I can bring all the plots to the same baseline if I want to do a comparison for example. More like stacking them on top of each other where they would technically overlap on each other.

Hello,
Have you tried to create an array with all the plots data before sending them to the graph?
Also this information might be helpful for you.

Here it is a way to handle Stack Plots or Overlay Them in a Waveform chart.

Do you just want to remove different dc offsets of your channels? That's just an add/subtract once you find the offset.

[ritch_by_nature]

I am able to do that.  i guess when i remove the offset i expected them to have similar baseline. 

[Dennis_Knutson]

If you remove the dc offset, then the baseline for each should be about the same. Similar to doing an acquisition with ac coupling though not quite as precise on my experience. Show how you are calculating the offset. How much difference in the baseline are you actually seeing?

This is how I do my offset and stack
