empty png

Using bqplot 0.10.1 on Ubuntu, I’m unable to save any png. It just creats an empty image.

This happens with both APIs, either using the save widget or the fig.save_png.

from bqplot import pyplot as plt

plt.figure(title='My First Plot')
plt.plot(x_data, y_data)
plt.show()

from bqplot import *

x_sc = LinearScale()
y_sc = LinearScale()

scatter_chart = Scatter(x=x_data, y=y_data, scales={'x': x_sc, 'y': y_sc})

x_ax = Axis(label='X', scale=x_sc)
y_ax = Axis(label='Y', scale=y_sc, orientation='vertical')

fig = Figure(marks=[scatter_chart], axes=[x_ax, y_ax])
fig.save_png()

Any clues?

By the way, thanks a lot for such an awesome library.

@lincolnfrias I think we’ve had a good bit of issues with non-Chrome browsers. @SylvainCorlay should we consider saying Chrome is our supported browser?

Great tip, @DougRzz. It worked on Chrome in my Ubuntu 16.04. Thanks a lot. So, at least in my case, it seems to be an issue in Firefox (58). I even disabled uBlock Origin, since I had problem with it on similar situations, but it didn’t solve this issue.
