Smoothen heatmap in plotly

Question

I wanted to create a heatmap of a probability density matrix using plotly.

import numpy as np
from plotly.offline import download_plotlyjs, init_notebook_mod         


        

Answer 1

You can use the zsmooth argument which can take three values ('fast', 'best', or False). For example:

data = [go.Heatmap(z=[[1, 20, 30],
                      [20, 1, 60],
                      [30, 60, 1]],
                   zsmooth = 'best')]
iplot(data)

Will give you the following smooth heatmap:
