I searched and couldn’t find a similar topic but I assume this has to exist so I apologize if this is a duplicate. I am collecting numbers on Screen 1, 2, and 3. I can aggregate the numbers (from one screen) into a list on screen 4 and create a dotplot. Can I aggregate across all three screens easily - I don’t believe the ‘and’ function works since they are numbers and not booleans.

# Combine two Lists into one

Our graph team is *AMAZING* and has a function for that:

`C_{oncat}\left(L_1,L_2\right)=\sum_{n=\left[1...\operatorname{length}\left(L_1\right)+\operatorname{length}\left(L_2\right)\right]}^{\left[1...\operatorname{length}\left(L_1\right)+\operatorname{length}\left(L_2\right)\right]}\left\{n\le\operatorname{length}\left(L_1\right):L_1\left[n\right],L_2\left[n-\operatorname{length}\left(L_1\right)\right]\right\}`

Just paste into a graph expression line and either create your lists or change the references in the function. Credit @aknauft

I’ve used this example to help with ideas in the past. Would the Concatenate Lists folder work as well?

That. Is. Amazing!

Thank you so much!
