What does the "srouce=" parameter does?

Dror_AtariahFeb 27, 2015 #1

For example in this simple example:

df = pd.DataFrame(from_some_dict)
tmp = ColumnDataSource(df)
p = figure()
p.scatter(df[‘datetime’], df[‘val’], source=tmp)
show(p)

I couldn’t figure out where to find the related documentation

you would either do:

p.scatter(‘datetime’, ‘val’, source=tmp)

p.scatter(df[‘datetime’], df[‘val’])

the reason you would use source explicitly is to do something like this:

p = figure()

p.scatter(‘datetime’, ‘val1’, source=tmp)

p2 = figure()

p2.scatter(‘datetime’, ‘val2’, source=tmp)

show(VBox(children=[p, p2])

If you do this, then p1/p2 are connected (linked brushing)
