Somewhat-related fio question: how do you make graphs of you results? For instance, I would like to show, say iops for 4K from write, randwrite, read, randread on the same drive comparing fio+libaio, fio+spdk, spdk+perf. This smells like a 3D graph thingie, but my lack of skills on excel/libre office does not help me. gnuplot?
