CORRECTION TO Vectorized Colors and Sizes

Community Support
1

I was studying the example on Vectorized Colors and Sizes,

THIS DOES NOT WORK:

colors = ["#%02x%02x%02x" % (r, g, 150) for r, g in zip(np.floor(50+2*x), np.floor(30+2*y))]

ERROR: TypeError: %x format: an integer is required, not numpy.float64

THIS WORKS:

colors = ["#%02x%02x%02x" % (int(r), int(g), 150) for r, g in zip(np.floor(50+2*x), np.floor(30+2*y))]

Took me quite a while, but I learn something.

Can you provide the exact URL you were looking at? I think you were looking at a link for an old version, since this was changed some time ago, at least in one place but maybe there are others.

Thanks,

Bryan

Oh, there is a newer version of the documentation?

I was looking at this:

http://bokeh.pydata.org/en/0.10.0/docs/quickstart.html

Hi,

yes the latest docs for the most recently released version are always at:

  Bokeh documentation — Bokeh 3.3.2 Documentation

It does look like this has been updated in the latest docs:

  http://bokeh.pydata.org/en/latest/docs/user_guide/quickstart.html#vectorized-colors-and-sizes

Starting with version 0.11 the docs site also has a "version selection dropdown" in the upper left hand corner, which should make it easier to get to the latest version of the docs going forward.

Thanks,

Bryan
