Bokeh Gmap hide/unhide background

Thanks for your
thoughts Arjuna. Feel free to open a feature request on bokeh’s github.

B ut off the top of my
head it seems unlikely
that this would be something for bokeh core. This s hould
be do able with either
CustomJS a CustomModel
or the bokeh server - or any combination
of them

                              I'm not sure

whether saving google 's tile
backgrounds would violate th eir
API. But regardless this
should be easy to imple ment
as a CustomM odel
also.

Best,

Bird

    I think it could be usefull to implement a tool to

hide/unhide the google map background in a bokeh GMap object.
Maybe some JS could do the job.
And maybe a way to save to PNG the background too, not only
the glyphs.

thanks

I was going to suggest a CustomJS callback to set GMapPlot.map_options in a way that makes everything invisible. That would probably be fairly straightforward. We can't just "turn off" the gmap completely as we rely on gmap to drive pan/zoom events.

Hi,

I was able to do more investigation, and I am afraid this is not something that will currently work. I had hoped to get you started with this quick example:

    from bokeh.io import output_file, show
    from bokeh.models import GMapPlot, Range1d, CustomJS, Button, VBox, GMapOptions

    map_options = GMapOptions(lat=30.2861, lng=-97.7394, map_type="roadmap", zoom=13)
    plot = GMapPlot(x_range=Range1d(), y_range=Range1d(), map_options=map_options)

    button = Button()
    button.callback = CustomJS(args=dict(plot=plot), code="""
        plot.map_options['styles'] = ### JSON map style string goes here
    """)

    output_file("foo.html")
    show(VBox(children=[button, plot]))

Unfortunately, it did not work, and after a little digging, I can see that the google map, and its options are only initialized once. Changing the map options does not have any effect later. I do think that changing map options later should be supported (and possibly even a show/hide functionality too). But it will rely on future work. I'd encourage you to submit a GH feature request, and reference this mailing list thread in the issue.

Sorry, I don't have better immediate news for you,

Bryan
