I have a series of results of some hadoop experiments. There are more than 500 datapoints (each experiment) and I want to show the overall timing. I'm asking for an effective way to plot this dataset (1 graph per experiment obviously). I'm not sure about an 'ordered' scatter plot like this (actually there is no real order but the timing order, the X value here is just a progressive number):
In this case I don't like the boxplot solution, sometimes the Q1 and mean are too close and the boxplot looks confusing. Maybe a normal distribution to visually show the mean and variance, there are tools for generate a normal distribution linegraph from data?
