Yes, an animation function, this applies for any graphic. See "Image updates" in the # create a `Plot` instance
plot_v = Plot()
# make some random data
data = np.random.rand(512, 512)
# plot the data
plot_v.add_image(data=data, name="random-image")
# a function to update the image_graphic
# a plot will pass its plot instance to the animation function as an argument
def update_data(plot_instance):
new_data = np.random.rand(512, 512)
plot_instance["random-image"].data = new_data
#add this as an animation function
plot_v.add_animations(update_data)
# show the plot
plot_v.show() |

I think the easiest way for you to do this right now is using two separate processes and sending the data to be plotted over zmq: https://github.com/fastplotlib/fastplotlib/tree/main/examples/notebooks/multiprocessing_zmq |
