Hey /gd/
Do you know the feeling when you are stuck with a complex project, because you cant think of new things except for the ones you already experinced?
I'm studying Interaction design at the local university and i'm working on an interactive informational system in which i need to show my data without typography or icons. So its more like a semantic exercise.

Now here's the problem:
I need to show 3 values and their average value at the same time to compare it to other 3 values and their average value.
For example in a ring graph: The additon of the 3 values result in the size of the graph, thus its 3 times the average and, thus, somehow the average, if all other average values are 3 times itself too. so thats okay,
but the bigger problem is that just the 3 radiants addet to each other is not semantically correct (pic related). As you can see on the left ring graph, the surface area of the second ring is bigger then the surface area of the inner ring, but the values are the same. I solved that with the square roots of the additions, as you can see on the right side.

Thats the part im stuck at, i can`t think of other semantically correct graphs to show my data.

tl;dr:
cant think of other semantically correct graphs that show 3 values and their average value to compare to other 3 values and their average.

Sorry for my english, its the first time for me to try to explain something like this in english.
