Image widget not showing.

[michiboo]

Hi I was trying to show image with Ipyastroimage with input being numpy array
Input:
color_scale = bqplot.ColorScale() scale_x = bqplot.LinearScale() scale_y = bqplot.LinearScale() image = AstroImage(image=data, scales={'image': color_scale, 'x': scale_x, 'y': scale_y})

Output:
AstroImage(image=array([[ 4.1139283, 4.4903197, 4.6050134, ..., 5.6953917, 9.383944 , 10.25792 ], [ 4.670872 , 5.606509 , 5.4989924, ..., 3.6070461, 5.371789 , 6.604827 ], [ 4.3647394, 5.54057 , 6.055377 , ..., 3.5973377, 4.83896 , 6.737476 ], ..., [22.368206 , 11.044641 , 4.1607943, ..., 3.3912497, 4.3756213, 3.659427 ], [ 9.733774 , 6.5522428, 3.4279304, ..., 2.7059777, 2.4026213, 2.7714913], [ 4.641999 , 3.700842 , 3.0346284, ..., 3.0442555, 2.8392305, 3.0797014]], dtype=float32), interactions={'hover': 'tooltip'}, scales={'image': ColorScale(), 'x': LinearScale(), 'y': LinearScale()}, scales_metadata={'x': {'orientation': 'horizontal', 'dimension': 'x'}, 'y': {'orientation': 'vertical', 'dimension': 'y'}, 'image': {'dimension': 'color'}}, tooltip_style={'opacity': 0.9})

As you can see only AstroImage follow by arguments value is shown

Then I try to put it in bqplot figure by using following:
fig = bqp.Figure(marks=[image])
display(fig)

still it didn't shown anything.

If you have any idea what might the problem, please let me know.

Thanks!

This needs a special branch of bqplot, we use it with mybinder with this setup script:

I hope that helps.
