I want to create a bar graph from multiple student entered data. Each student will run a simulation 10 times and I want them to record their wins and losses. I then want a bar graph the displays the total number of wins and losses for everyone in the class. I was imagining they could enter an L or W into a table with 10 entries and create a bar graph from that data. Is this possible?
I think this should help: You can use this historgram function to translate a table into a bar graph, or basically any plot you want.
Yeah, I’ve always found aggregate a little tricky when the data isn’t naturally numeric.
I put together a small example which might be something like you’re looking for? You can find the activity here
It just hard-codes ingesting the student data on the first page like so
and then aggregates the totals on the next page
I avoided using the histogram function in the desmos graph since the aggregated data isn’t actually the original data, just frequencies from individual students 
The graph can be found here, and calculates a t_{otal} variable, just because I was originally using this for doing relative frequencies rather than total counts.
Hope this helps! Someone more familiar with CL might know a cleaner way to do this
