Annotate heatmap with value from Pandas dataframe

Question

I would like to annotate a heatmap with the values that I pass from a dataframe into the function below. I have looked at matplotlib.text but have not been able to get the value

Answer 1

You also can use plotly.figure_factory to create heatmap from DataFrame, but you have convert it into list.

    import plotly.figure_factory as ff

    z = [your_dataframe].values.tolist()
    x = [your_dataframe].columns.tolist()
    y = [your_dataframe].index.tolist()

    fig = ff.create_annotated_heatmap(z, x=x, y=y, annotation_text=z, colorscale='viridis')

    # for add annotation into Heatmap
    for i in range(len(fig.layout.annotations)):
        fig.layout.annotations[i].font.size = 12

    # show your Heatmap
    fig.show()
