Hola, I have 2 Graph Builder questions: 1. In a scatter plot, why is it possible to add error bars to the mean but not the median? Could someone please offer advise on how to get around this? 2. How can you use more than one overlay condition? e.i. I want to graph leaf area (Y variable) by leaf age (X variable= 9 different ages) using two overlays for the Y variable as follows: Overlay 1 = tree (4 different trees) Overlay 2 = canopy position (2 different canopy positions: sun and shade) So that I end up with a single line graph with 2 lines for each tree, one for sun leaves and one for shade leaves. I have tried this before but Graph Builder only accepts one overlay. My data is arranged in 4 different columns: 1 for leaf area, 1 for leaf age, 1 for tree number and 1 for canopy position. I have a bit of experience making small modifications to scripts that graph builder creates but I am not a programmer and my attempts have been unsuccessful so far, I would very much appreciate any help on this. Many thanks in advance for the help, Cecilia
