【问题描述】:
我正在查看这个 matplotlib 散点图示例: https://matplotlib.org/examples/shapes_and_collections/scatter_demo.html
"""
Simple demo of a scatter plot.
"""
import numpy as np
import matplotlib.pyplot as plt
N = 50
x = np.random.rand(N)
y = np.random.rand(N)
colors = np.random.rand(N)
area = np.pi * (15 * np.random.rand(N))**2 # 0 to 15 point radii
plt.scatter(x, y, s=area, c=colors, alpha=0.5)
plt.show()
我尝试通过利用 matplotlib 在 Bokeh 中完成同样的任务:
import numpy as np
import matplotlib.pyplot as plt
from bokeh.plotting import output_file, show
from bokeh import mpl
N = 50
x = np.random.rand(N)
y = np.random.rand(N)
colors = np.random.rand(N)
area = np.pi * (15 * np.random.rand(N))**2 # 0 to 15 point radii
plt.scatter(x, y, s=area, c=colors, alpha=0.5)
output_file("scatter_demo.html")
show(mpl.to_bokeh())
如何调整圆的半径?我确信它可以通过纯 Bokeh 来完成,但我希望使用依赖于 Matplotlib 的 Bokeh 进行更高级的绘图,所以我希望使用 show(mpl.to_bokeh())。谢谢!
在运行 Bokeh 脚本时,我也收到此警告:
/Users/tc9/lib/python3.6/site-packages/bokeh/core/compat/bokeh_renderer.py:263: UserWarning: Path marker shapes currently not handled, defaulting to Circle

编辑:散点图的等效散景演示示例如下: http://docs.bokeh.org/en/latest/docs/gallery/color_scatter.html
