python - 如何使用matplotlib和numpy绘制热力图

Question

现有3个list

x = [x0, x1, x2, ..., xn]
y = [y0, y1, y2, ..., yn]
v = [v0, v1, v2, ..., vn]

希望可以据此生成热力图，效果类似http://stackoverflow.com/questions/21663358/gnuplot-heatmap-xyz 答案里的效果。搜索了一些类似的问题但是好像不太一样(http://stackoverflow.com/questions/14391959/heatmap-in-matplotlib-with-pcolor).

谢谢！

Maybe you can refer to the content of the link below

In addition, if you are not limited to matplotlib, you can try Plotly
