[英]Polar map from existing Cartesian coordinates and phi values in matplotlib
I am trying to plot a polar colour heat map for a set of coordinates (coor) and corresponding phi values.我正在尝试 plot 极色热 map 一组坐标 (coor) 和相应的 phi 值。 I have used the tripcolor function as follows:我使用了 tripcolor function 如下:
plt.tripcolor(coor[:, 0], coor[:, 1], phi, shading=shading, cmap=cmap, edgecolor="face")
plt.show()
This is the result that I got: PlotMesh这是我得到的结果: PlotMesh
Is there a way to make the outer grid circular?有没有办法使外部网格呈圆形?
I would try to create a triangulation from the coordinates:我会尝试从坐标创建三角剖分:
import matplotlib.tri as tri
triang = tri.Triangulation(coor[:, 0], coor[:, 1])
plt.tripcolor(triang, phi, shading=shading, cmap=cmap, edgecolor="face")
