I have a scatter(log-)plot with some 10,000 data points that plots the running time of some algorithm against the input on random instances of some problem.
I have a lot of these plots, and due to space constraints I can't exactly dedicate a large amount of space to them. The plots are 1-2 inches tall. The trouble is that a handful (maybe 5 or so) of these samples have taken a ridiculously short amount of time to complete (say, a few milliseconds), whereas pretty much all of the other data points have taken 2-3 orders of magnitude longer.
I'm trying to show that my algorithm is fast, so I figure it shouldn't hurt to just omit these handful of data points and generate more samples, right?
I feel like mentioning anything would unnecessarily confuse the reader, and keeping them would annoy the reader since the plot would have a large amount of blank space. And obviously it's not like I'm trying to suppress evidence against my research or something---the discarded data is only in favor of my algorithm.
Would I be violating some ethical code here if I just discard those samples without mentioning anything so that my plots look nicer? Is it unscientific? And if so would anyone actually care?
