Hi I have a rather basic question regarding color. Is there a way to specify a different color for a bar chart or any type of chart where value is greater than some value?
Right now, its simply:
q1 = Bar(topics, label=‘Topic’, values=‘Number of Posts’, title=“Total posts”)
show(q1)
Like I want maybe a green color if ‘Number of Posts’ > 300
Thanks 
Hi Mudit,
The high level charts interface is intended to to make the commonest cases completely trivial. To exert more control, you'll probably want to look at the mid-level bokeh.plotting interface. You can see an example of bar-like plots using the "quad" glyph function here:
http://bokeh.pydata.org/en/latest/docs/gallery/histogram.html
With bokeh.plotting you can easily set the individual colors for bars (or whatever glyphs you are display) by setting the "fill_color" property to list of colors. For example, this example shows individually coloring individual circles:

Hi Mudit,
That's a
really interesting i dea, it reminds me of the ideas in
DataShader where you can apply “visual transforms”
Best,

Bryan’s already answered how you could do this for now, but if you could
open a github issue
for this feature idea, that would be great.
