defcon plot
defcon plot1206×1227 13.3 KB

It’s been six years since I’ve done anything with Bokeh or python( I’m retired). I’m trying to do a simple scatter plot with minimal data. When I run the cell in jupyter no errors are thrown and I get an html page with the title and zoom buttons but the page is blank. I’m running Bokeh 3.8.2 & python 3.13.9. I’m certain it is something simple, I’m just not seeing it. Thanks in Advance.

here is the cell and data I’m using and a png file of the output.

import pandas
from bokeh.io import show
from bokeh.plotting import figure

df = pandas.read_csv(r’C:\Users\jeski\bokeh\top-ten-defcon.csv’)
print(df[[“DefCon”, “Name”]])
fig = figure(width=800, height=800, title=“Defcon Plot”)

#fig.circle(x=[“Name”], y=[“Defensive Contribution”])
fig.scatter(x=df[“Name”], y=df[“DefCon”], size=8, color=“orange”)
show(fig)

@bitterandstout Just to be clear you are trying to create a page outside the notebook? If you want the outputs to display inline in notebook cells, you’d need to execute output_notebook at the top of your code. But assuming you want a separate HTML page generated, the code above looks fine, so maybe there is some environment or version mismatch issue. Are there any errors or messages reported in the browser’s console log when you view the blank page?

@bitterandstout Sorry I should have looked closer before replying. It looks like one of the columns you are plotting is strings? By default Bokeh plots assume numerical ranges, so you’ll need to configure an appropriate categorical range if the data consists of string values. It’s usually as simple as passing something like this (untested) to figure:

x_range=list(df["Name"].unique())

Here is the user guide chapter on dealing with categorical data:
