Close figures created using plotly

[cishwarya]

I have a quick question. I have recently started to use plotly offline.
I am running machine learning experiments which saves huge amount of images, in the order of 100s.
I want to close the figures created using plotly.

Previously, I have used matplotlib library, where I used matplotlib.pyplot.close() to close the figures. I would like to know the equivalent of this in plotly.
Can you please help me in this regard?

Hi @cishwarya,

This might not be possible but I would like to understand your use case a little better. How are you displaying the plotly figures (e.g. with iplot in the notebook, with plot in the browser, etc.)? In what format do you want to save them to disk (standalone HTML files, static images, etc.)?

Thanks!

Hi,
I have the same problem.

I have code similar to this.

import numpy as np
import plotly.express as px
for i in range(1000):
   x = np.random.rand(6,6)
   fig = px.imshow(x)
   fig.show()
   fig.write_image(f"mycool_array_{i}.png"

I seem to have trouble getting it to save the images properly.

@cishwarya
Perhaps resetting the figure and re-using it does the trick for you ? It did for me.

Remove all traces

Hi @KidSampson, glad you’re enjoying the library! You can remove all traces for a FigureWidget by assigning an empty list the the data property fig.data = [] You can also remove only select traces by assigning the data property to a subset of itself. So to remove the second trace, but keep the first and third trace: fig.data = [fig.data[0], fig.data[2]] If you need to clear the layout as well, assign an emtpy dict to the layout property fig.layout = {} Hope that helps! -Jon

@garland3
fig.show() clears the image.

switch the order

   fig.write_image(f"mycool_array_{i}.png")
   fig.show()
