I'v always been confused about Maalam. I personally vote for Bayani (for Rasm Bayani) so it would be obvious.
+ Bayani (related to 'graph') + Muqawas (related to 'curve') + Watar (related to 'sinew') + Nuqta (related to 'point') + Mukhatat (related to 'plot') + Mehwar (related to 'axis') + Shabaka (related to 'grid') + Munaseeq (related to 'coordinate') + Aseel (related to 'origin') + Hawiya (related to 'container')
Sorry again for this nontechnical mumbo-jumbo & Salam.
