How can I accomplish `set_xlim` or `set_ylim` in Bokeh?
Maybe a naive solution, but why not passing the lim axis as argument of your function?
import numpy
from bokeh.plotting import figure, show, output_notebook
output_notebook()
def make_fig(rows=16, cols=16,x_range=[0, 16], y_range=[0, 16], plot_width=500, plot_height=500):
img = numpy.ones((rows, cols), dtype=numpy.uint32)
view = img.view(dtype=numpy.uint8).reshape((rows, cols, 4))
view[:, :, 0] = numpy.arange(256)
view[:, :, 1] = 265 - numpy.arange(256)
fig = figure(x_range=x_range, y_range=y_range, plot_width=plot_width, plot_height=plot_height)
fig.image_rgba(image=[img], x=[0], y=[0], dw=[cols], dh=[rows])
return fig
One way is to can things with a simple tuple when creating a figure:
figure(..., x_range=(left, right), y_range=(bottom, top))
But you can also set the x_range
and y_range
properties of a created figure directly. (I had been looking for something like set_xlim
or set_ylim
from matplotlib.)
from bokeh.models import Range1d
fig = make_fig()
left, right, bottom, top = 3, 9, 4, 10
fig.x_range=Range1d(left, right)
fig.y_range=Range1d(bottom, top)
show(fig)
As of Bokeh 2.X, it seems it is not possible to replace figure.{x,y}_range
with a new instance of Range1d
from DataRange1d
or vice versa.
Instead one has to set figure.x_range.start
and figure.x_range.end
for a dynamic update.
