Add values to figure according to categorical y-axis

Community Support
1

Hello,

I wondered if its possible to add markers to a figure refering to the catecorical y-axis. This is the example:

from bokeh.plotting import figure, output_file, show

factors = ["a", "b", "c", "d", "e", "f", "g", "h"]
x = [50, 40, 65, 10, 25, 37, 80, 60]

output_file("categorical.html")

p = figure(y_range=factors)

p.circle(x, factors, size=15, fill_color="orange", line_color="green", line_width=3)

show(p)

And I would like to do something like this:

p.triangle(x=x_value, y=“a”)

so the triangle shows up at the coordinates (x_value,“a”)

Best regards,
Charlotte

Hi,

By default, strings are interpreted as column names. This is the best correct thing in the majority of situations, but there are a a few ambiguous cases where it can be ambiguous (basically whenever a string could also be a value). You probably will need to tell Bokeh explicitly that "a" is a value, and not a column name:

  from bokeh.core.properties import value

  p.triangle(x=x_value, y=value("a"))

Thanks,

Bryan

Hey,

thanks for this quick reply!

Now it gives me the following error:

Number property 'y' given invalid value: a

Hrm, this seems like a bug. Please file a bug report on GitHub with a complete code sample to reproduce. In the mean time, the best workaround I can offer is:

   p.triangle(x=x_value, y=v['a']*len(x))

which I confirmed worked.

Thanks,

Bryan

I’m not sure what is meant by v[‘a’] ?

I’ll file a bug report!

Thanks,
