About plot_roofline.py

[mahmoodn]

I ran plot_roofline.py with the default data.txt file to see how it is working.
While the data file contains

memroofs 828.758
mem_roof_names 'HBM'
comproofs 7068.86 3535.79
comp_roof_names 'FMA' 'No-FMA'

# omit the following if only plotting roofs
AI 2.584785579
FLOPS 2085.756683
labels 'FMA, nw=1' 'NoFMA, nw=2'

I only see one legend which is "FMA, nw=1". So, why "NoFMA, nw=2" is not shown? Sounds like a bug. Is that normal?

Also what are AI and FLOPS lines? Where are these information plotted in the chart?
