Save tool in gridplot initiates multiple downloads

ALL software version info (bokeh, python, notebook, OS, browser, any other relevant packages)

Bokeh 1.0.3 Python 3.5

Description of expected behavior and the observed behavior

Clicking ‘save’ tool on gridplot() downloads each subplot separately. Preferably, if the tools are merged, so would the plots be merged into a single image.

Complete, minimal, self-contained example code that reproduces the issue

import numpy as np
from bokeh.io import show
from bokeh.layouts import gridplot
from bokeh.plotting import figure


plots = []
for i in range(10):
    p = figure(plot_height=70,
               tools='save')
    p.line(np.arange(10), np.random.random(10))
    plots.append(p)

p = gridplot(plots, ncols=1)
show(p)

export_png() and save tool are two different things. There was no progress on this issue so far.

It is actually working (at least on Mac) using the export_png() method so I guess it’s been already implemented in 1.0.4… See this post
