Plate label appears in a blue box

Hello! I can’t figure out this behavior. This code (see below) produces the right figure but the plate label is colored (see fig):

pgm = daft.PGM(shape=[2., 4.], # width, height
               origin=[0, 0], 
               grid_unit=4,
               label_params={'fontsize':20}, 
               observed_style='shaded')

pgm.add_node(daft.Node("R", r"$R$", 1, 0.5, scale=2))
pgm.add_node(daft.Node("alpha", r"$\alpha$", 1, 1.5, scale=2))
pgm.add_node(daft.Node("r", r"$r$", 1, 2.5, scale=2))

pgm.add_node(daft.Node("xi", r"$\xi$", 1, 3.5, scale=2,
                       fixed=True, offset=(0,10)))

pgm.add_plate(daft.Plate([0.5, 0.1, 1, 3.0], r"$k=0,...,11$",position='bottom right', rect_params={fill:False}))


# draw directed edges
pgm.add_edge("alpha", "R")
pgm.add_edge("r", "alpha")
pgm.add_edge("xi", "r")

pgm.render()

)

Otherwise, it’s a great package! Thanks for the work!

OK. Here’s what I get when I run your code on matplotlib v2.2.0:

I am fairly confident that you must have some default matplotlib settings somewhere.

A few options:

1. Look into how matplotlib is customized and make sure that you’re not using any customizations (e.g. a matplotlibrc file somewhere)
2. Add:

import matplotlib as mpl
mpl.rcParams.update(mpl.rcParamsDefault)

1. Add: bbox={"color": "none"} to the daft.Plate instantiation

Hope this helps!

Thanks for the tips! The last one worked 😉 It’s a bit of a hack but it works for me.
