Hello, I have the following csv file n, n_red 1, 0 1, 1 2, 1 2, 1 3, 0 4, 1 4, 2 4, 3 I would like to plot this data. On the x-axis there should be n and on the y-axis the mean of all n_red where n is the according value on the x-axis. The plot should look like plotting the following data: n, n_red 1, 0.5 2, 1 3, 0 4, 2 Is there any simple way to do this? Greetings odif
