Polar contour plot / Contourpolar request

Hi!

Your plotting library is really awesome! Thanks for that!

I'm currently trying to make the switch from matplotlib (for Python plots) to Plotly (also Python) and I was looking for an option to display contour plots in a polar coordinate system.

I came across the following issue in plotly.py where @emmanuelle suggested to create a post here in plotly.js.

Do you guys have the intention of creating a Contourpolar type of chart? Similar to the plot show below (created in matplotlib):

I've tried the Barpolar option, but it's not sufficient for the amount of detail I would like to visualize (a 360 degree water surface elevation plot), I think the plot I would like to display greatly benefits from being a contour plot.

Thanks in advance,
Sil

この Issue では、ファイル、テスト、エントリーポイントが特定されていません。まず、Plotly.js が polar trace と contour trace をどのように表現しているかをたどり、次に Contourpolar chart に必要な範囲を特定してください。極座標で詳細なデータを表示できる contour plot が実現し、関連するテストでカバレッジが確保されていれば完了です。
