This relates to this Stack Overflow question.
I’m new to python, plotting, and bokeh, so I’m hoping I’m doing something wrong that is quite simple.
Something breaks when I try to change the size of plot markers on a scatter plot to reflect the value count of a column of data.
Here’s a link to the .py file. I removed any sensitive data (credentials), but kept everything else as is.
I was getting a successful plot (1st image, further down), but when I added the below to try and change the marker sizes it gets screwy (2nd image):
Variable for the frequency count of Control Form Groups (for scatter plot)
cfg_freq = data[‘cfg’].value_counts()*4
``
Changed the size:
Set up the plot points, including the Hover Tool
cr = wt_cfg_plot.scatter(WT_Number, CFG_Number, size=cfg_freq, fill_color=“blue”,
line_color=None, alpha=0.7, hover_fill_color=“firebrick”,
hover_line_color=None, hover_alpha=1)
``
The 1st Image. All is good so far. For this size=7
The 2nd image, with the new size applied. Shenanigans. At the bottom is the full error message. The linked .py file has the code as it was.
The full error message:

I’ll finish this by saying that I have no idea how to successfully change the marker sizes by value in any other package. This is all pretty much the first time I’m doing any of it, I’m learning as I go!
