Updating y_range to categorical

Fraser1Aug 23, 2017 #1

I’m attempting to define the axis range as categorical once the figure is declared, and I’m running into errors. Here’s my demo code (Bokeh 0.12.6):

from bokeh.plotting import figure, output_file, show
from bokeh.models import FactorRange
factors = [“a”, “b”, “c”, “d”, “e”, “f”, “g”, “h”]
x = [50, 40, 65, 10, 25, 37, 80, 60]
output_file(“categorical.html”)
p = figure()
p.y_range = FactorRange(factors=factors)
circle = p.circle(x, factors, size=15, fill_color=“orange”, line_color=“green”, line_width=3)
show(p)

This throws the error “Range FactorRange is incompatible is Scale LinearScale”. If I initially declare the figure as follows, it works:

p = figure(y_range=factors)

What am I doing wrong? A more general question might be, is there a general way to update p = figure(foo=bar) after figure() is called?

Thanks for your help! I’ve been stuck on this for days.

In addition, I have also tried:

p.y_range.factors = factors

However, factors is not an attribute of y_range.

Hi,

You want to do this when you *create* the figure (that is the easiest way by far)

p = figure(y_range=factors)

The lots of coordination of different low level objects will happen auto-magically. Otherwise, you will have to take care to set up lots of low level building block pieces by hand.

And to add:

There are lots of different kinds of ranges. Only one of them (FactorRange) has .factors as an attribute, but FactorRange is not the default range because most plots are not categorical.

OK - I will take your advice and rework things so it happens automagically. Thanks for your help, Bryan!

If you pass factors to figure initially, then y_range will be a FactorRange, you can always set its .factors to something different later.
