Hi Arthur,
Here’s a code snippet inspired by Sarah’s notebook that should do what you were asking for:
from bokeh.plotting import *
from collections import OrderedDict
from bokeh.models import HoverTool, Range1d
from bokeh.models import Text
source = ColumnDataSource(
data=dict(
x = [2, 3, 7],
y = [4, 2, 3],
text = [“Hello”, “Bokeh is great”,“Thanks for you help”]
)
)
output_file(“scatter.html”, title=“scatter.py example”)
p = figure(tools=“pan,wheel_zoom,box_zoom,reset,save,hover,crosshair,box_select”)
p.scatter(‘x’,‘y’, color=“red”, source=source)
hover =p.select(dict(type=HoverTool))
hover.tooltips = OrderedDict([
(“(x,y)”, “($x, $y)”),
(“text”, “@text”),
(“x”, “@x”),
(“y”, “@y”)
])
def construct_text_box(source):
Plot and axes
xdr = Range1d(0, 220)
ydr = Range1d(0, 120)
plot = Plot(x_range=xdr, y_range=ydr, title=“”, plot_width=250,
plot_height=120, min_border=0)
txt1 = Text(x=0, y=0, text=‘text’, text_color=“white”)
txt2 = Text(x=10, y=10, text=‘text’, text_font_size=‘18pt’,
text_color=“#2B292E”)
plot.add_glyph(source, txt1, selection_glyph=txt2)
return plot
txtbox = construct_text_box(source)
show(hplot(p, txtbox))
``
Cheers
Fabio

Hi Sarah,
Thanks for the link. I can’t get a minimalist example to work.
Can you (or anyone else) build a minimalist example based on:
x,y,text
2,4,“Hello”
3,2,“Bokeh is great”
7,3,“Thanks for you help”
Thanks !
Arthur

Yes!
Have a look at the example here: http://nbviewer.ipython.org/github/birdsarah/pycon_2015_bokeh_talk/blob/master/notebooks/Building%20the%20static%20visualization.ipynb
If you scroll all the way to the bottom you will see that when you click a country, the text in the right box changes.
Hopefully you can get what you need from the code there.
Sincerely,
Sarah Bird

Hi.
I’ve a scatter plot. Each point has a text field. My data is like:
x,y,text
2,4,“Hello”
3,2,“Bokeh is great”
7,3,“Thanks for you help”
Can the text be shown in a separate text plot (next to the scatter plot) plot when I click the point in the scatter plot ?
Thanks !
ARthur
