Is there near plan to add more documents?

Great tools!
and I have several questions.
how to create different visdom workspace programmingly?
Is it possible to make the following code work if the window 'loss' has not been initiated before. It's quite inconvenient if I have to create every window first using some dammy data and then update it.

viz.line(
    X = np.asarray([0]),
    Y= np.array([10]),
    win='loss',
    update='append'
)

Thank you~

The win does not need to exist when you specify it. What do you need dummy data for? A code setup like this should work just fine:

win = None
for n in range(N):
   data = #...
   win = viz.plot(X=data, win=win)

This code pattern is used in this Lua example: https://github.com/facebookresearch/visdom/blob/master/example/demo2.lua#L99-109

Thank you for your reply.
But in my case, I'd prefer win be a pre-specified 'string', because later I need to get access to the same figure in another place. If I use None as Win, it seems that it will return a very complex string rather than a meaningful one. I used the following workaround, but there should be a better one.

    win = name + '_loss'
    res = plot.line(
            X = steps,
            Y=  values,
            win= win,
            update='append'
        )
    if res != win:
        plot.line(
            X = steps,
            Y=  values,
            win=win
        )

Fot the line-plot, is there anyway to get access to the data (X, Y) stored in the figure? Because when I re-run a program, the index start from 1 again, but I want to append it to the end of the figure, rather than creating a new figure.
Thank you!

You can use a pre-specified win string:

vis = visdom.Visdom()
win = visdom.text{text = 'test', win = 'my_window'}
print(win)

This will print 'my_window'.

There is currently no way to access the data on the server from the Python/Lua wrapper, but you can use the update='append' option to add new data to the existing data.

Thank you for your answering.
For example, I have already many pairs of (x,y) in a plot.
But then I re-load my program and want to append new data points to the end of that plot.
But the current x will start from 1 again and I don't actually know how many points in the original plot. so It will be hard to append to the right place.
Thank you~
