h/o, probably need to update our tests...

Hmm.

Off the issue-49 branch:

dataviz1 = plt.figure(...)
dataviz1_plotly = tls.mpl_to_plotly(dataviz1)
dataviz1_plotly['layout']['annotations'][i]['align'] # --> 'center' for all i's

Randal made his source and info annotation using

text(1966, -8, "Data source: nces.ed.gov/programs/digest/2013menu_tables.asp" 
 "\nAuthor: Randy Olson (randalolson.com / @randal_olson)" 
 "\nNote: Some majors are missing because the historical data " 
 "is not available for them", fontsize=10)

which generated a left-align multi-line annotation (see here)

This suggests that mpl multi-line annotations are in fact left-aligned; hence, the plotly convention should include 'align': 'text' in the corresponding annotation object.

haha, oh man! it's a weird default for mpl. if you specify that you want the 'center' the surrounding box and don't specify that the multialignment, the default is indeed 'center' as i had. HOWEVER, if you don't specify the horizontalalignment as is the case in your example, it seems that mpl defaults to 'left', woof!

@etpinard, correction, looks like it defaults to horizontalalignment when unspecified. that should fix it. although, again i probably have to change a test or two to catch up!

k, good to go!

Nice! 👍
