line append

I want to use line’s update=append parameter, like:

import visdom
import numpy as np

viz = visdom.Visdom()

win = viz.line(
    X=np.column_stack((np.arange(0, 10), np.arange(0, 10))),
    Y=np.column_stack((np.linspace(5, 10, 10), np.linspace(5, 10, 10) + 5))
)

viz.line(
    X=np.column_stack((np.arange(10, 20), np.arange(10, 20))),
    Y=np.column_stack((np.linspace(5, 10, 10), np.linspace(5, 10, 10) + 5)),
    win=win,
    update='append'
)

But second line do not showing.

The demo uses features that are not yet in the pip-version of visdom. Please install visdom from source if you need these features. See the relevant question here for details.

@QinZiwen try following the instructions on the main README for installing from source. Not all features in the demo have been put into the pip version.
