Bokeh 0.10.0

Laying Out Multiple Plots

Bokeh includes several layout options for arranging plots and widgets in an HTML document. Note that the layout options here are all HTML layouts; future Bokeh versions should offer the ability to lay out multiple sub-plots on a single canvas.

Vertical Layout

To array a set of plots in a vertical fashion, use the vplot() function:

from bokeh.io import output_file, show, vplot
from bokeh.plotting import figure

output_file("layout.html")

x = list(range(11))
y0 = x
y1 = [10 - i for i in x]
y2 = [abs(i - 5) for i in x]

# create a new plot
s1 = figure(width=250, plot_height=250, title=None)
s1.circle(x, y0, size=10, color="navy", alpha=0.5)

# create another one
s2 = figure(width=250, height=250, title=None)
s2.triangle(x, y1, size=10, color="firebrick", alpha=0.5)

# create and another
s3 = figure(width=250, height=250, title=None)
s3.square(x, y2, size=10, color="olive", alpha=0.5)

# put all the plots in a VBox
p = vplot(s1, s2, s3)

# show the results
show(p)

Horizontal Layout

To array plots horizontally, use the hplot() function:

from bokeh.io import hplot, output_file, show
from bokeh.plotting import figure

output_file("layout.html")

x = list(range(11))
y0 = x
y1 = [10 - i for i in x]
y2 = [abs(i - 5) for i in x]

# create a new plot
s1 = figure(width=250, plot_height=250, title=None)
s1.circle(x, y0, size=10, color="navy", alpha=0.5)

# create another one
s2 = figure(width=250, height=250, title=None)
s2.triangle(x, y1, size=10, color="firebrick", alpha=0.5)

# create and another
s3 = figure(width=250, height=250, title=None)
s3.square(x, y2, size=10, color="olive", alpha=0.5)

# put all the plots in an HBox
p = hplot(s1, s2, s3)

# show the results
show(p)

Grid Layout

Bokeh also provides a gridplot() function that can be used to arrange Bokeh Plots in grid layout. Note that gridplot() also collects all tools into a single toolbar, and the currently active tool is the same for all plots in the grid. It is possible to leave “empty” spaces in the grid by passing None instead of a plot object:

from bokeh.io import gridplot, output_file, show
from bokeh.plotting import figure

output_file("layout.html")

x = list(range(11))
y0 = x
y1 = [10-i for i in x]
y2 = [abs(i-5) for i in x]

# create a new plot
s1 = figure(width=250, plot_height=250, title=None)
s1.circle(x, y0, size=10, color="navy", alpha=0.5)

# create another one
s2 = figure(width=250, height=250, title=None)
s2.triangle(x, y1, size=10, color="firebrick", alpha=0.5)

# create and another
s3 = figure(width=250, height=250, title=None)
s3.square(x, y2, size=10, color="olive", alpha=0.5)

# put all the plots in a grid layout
p = gridplot([[s1, s2], [None, s3]])

# show the results
show(p)

Form Layout

To include widgets in a layout, it is currently necessary to put everything in a vform() layout. You can see an example of this in the section CustomJS for Widgets.

Note

Improving the spelling and ease-of-use of widget layouts is an area of active work.
