How can I accomplish `set_xlim` or `set_ylim` in Bokeh?

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 Range1dfig = make_fig()left, right, bottom, top = 3, 9, 4, 10fig.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.

See https://github.com/bokeh/bokeh/issues/8421 for further details on this issue.

Maybe a naive solution, but why not passing the lim axis as argument of your function?
