Make radius dimension configurable for circles

[bryevdv]

The notion of a "circle with radius" implicitly assumes 1-1 aspect ratio. If the aspect is not 1-1, the "proper" thing would be to draw ellipses. However, it is often desired to draw circles anyway, even with non 1-1 aspect As a practical matter we have to pick one dimension to measure screen distance along. Currently this dimension is fixed to be the x axis. Propose making the dimension configurable with a radius_dim parameter that takes the following values:

• "x" measure screen distance along x-axis
• "y" measure screen distance along y-axis
• "min" use min screen distance
• "max" use max screen distance

Just spoke to @bryevdv regarding this feature. My use case would be specify which axis to use. Currently to scale to y-axis values I need to multiply radius by plot_height/plot_width * x_range/y_range. Workable so feature isn't urgent but would be convenient.

Accidental push to master. Screenshot attached below (would have been in PR)

from bokeh.plotting import figure, output_file, show, VBox

p1 = figure(width=250, height=250)
p1.circle([2,4,6], [1000, 2000, 3000], radius=1)

p2 = figure(width=250, height=250)
p2.circle([2,4,6], [10, 20, 30], radius=1, radius_dimension='y')

output_file("foo.html")

show(VBox(p1, p2))

Hello

Please i intend to produce a bubble graph in Bokeh, but do not seem to find a way of supplying different values for size. A CDS with x,y and z columns. Have used p.circle(x,y, size=z, source=source), radius and radius_dimensions do not take a column. Any help please! Thanks

@Venedictos There are several ways to have many circles with different sizes, but GitHub is not the appropriate place to ask suppose questions. Please ask again on the Bokeh Discourse site

@bryevdv thanks. I will. Cheers
