Bokeh 或 Plotly 中的极坐标等值线图

Question

我需要使用 Bokeh 或 Plotly Python 绘制等高线图，以显示圆形区域中的波浪分布。我总是研究 49 个点，并且 x_cord 和 y_cord 是已知的，并且在不同情况下不会改变。波密度（z）可以通过python中的其他函数计算，并根据具体情况进行更改。

我在网上搜索并找不到解决方案。有熟悉 Bokeh/Plotly 的人可以提供帮助吗？

我要画的图是这样的：

谢谢！

这里是输入 x_cord、y_cord 和 z 的示例

x_cord = [0, -0.0, -34.6, -49, -34.6, 0.0, 34.6, 49, 34.6, -0.0, -37.5, -69.3, -90.5, -98, -90.5, -69.3, - 37.5、0.0、37.5、69.3、90.5、98、90.5、69.3、37.5、-0.0、-38.0、-73.5、-103.9、-127.3、-142.0、-147、-142.0、-127.3、-103.9、-73.5 , -38.0, 0.0, 38.0, 73.5, 103.9, 127.3, 142.0, 147, 142.0, 127.3, 103.9, 73.5, 38.0]

y_cord = [0, 49, 34.6, -0.0, -34.6, -49, -34.6, 0.0, 34.6, 98, 90.5, 69.3, 37.5, -0.0, -37.5, -69.3, -90.5, -98 , -90.5, -69.3, -37.5, 0.0, 37.5, 69.3, 90.5, 147, 142.0, 127.3, 103.9, 73.5, 38.0, -0.0, -38.0, -73.5, -103.9, -127.3, -142.0, -147 , -142.0, -127.3, -103.9, -73.5, -38.0, 0.0, 38.0, 73.5, 103.9, 127.3, 142.0]

Z = [0.932,0.93,0.93,0.932,0.933,0.933,0.932,0.931,0.93,0.924,0.925,0.926,0.927,0.928,0.929,0.929,0.929,0.93,0.929,0.928,0.927,0.926， 0.925,0.924,0.924,0.92,0.923,0.923,0.924,0.925,0.923,0.924,0.925,0.925,0.924,0.923,0.921,0.92,0.923,0.921,0.92,0.921,0.92,0.919,0.919,0.917,0.917， 0.918, 0.919]

在plotly 你可以得到类似的东西：

Code:
# import the necessaries libraries
import plotly.offline as py
import plotly.graph_objs as go
# Create data
data = [
    go.Histogram2dcontour(
          x = [0, -0.0, -34.6, -49, -34.6, 0.0, 34.6, 49, 34.6, -0.0, -37.5,\
               -69.3, -90.5, -98, -90.5, -69.3, -37.5, 0.0, 37.5, 69.3, 90.5,\
               98, 90.5, 69.3, 37.5, -0.0, -38.0, -73.5, -103.9, -127.3,\
               -142.0, -147, -142.0, -127.3, -103.9, -73.5, -38.0, 0.0, 38.0,\
               73.5, 103.9, 127.3, 142.0, 147, 142.0, 127.3, 103.9, 73.5, 38.0],
          y = [0, 49, 34.6, -0.0, -34.6, -49, -34.6, 0.0, 34.6, 98, 90.5, 69.3,\

# Layout usually need to set the title, size of plot etc.
