python - Outputting a Seaborn heatmap chart of a pandas DataFrame using Bokeh -

-

i'm trying plot seaborn heatmap chart , output using bokeh.

here's how plot chart:

in [1]: import pandas pd    ...: import seaborn sns    ...:     ...: df = pd.dataframe([['item1',1,2,3,4,'sept'],    ...:                    ['item2',5,6,7,8,'oct'],    ...:                    ['item3',9,10,11,12,'sept'],    ...:                    ['item1',13,14,15,16,'oct'],    ...:                    ['item2',17,18,19,20,'sept'],    ...:                    ['item3',21,22,23,24,'oct']],    ...:                    columns = ['itemname','metric1',    ...:                    'metric2','metric3','metric4','month'])    ...: df out[1]:    itemname  metric1  metric2  metric3  metric4 month 0    item1        1        2        3        4  sept 1    item2        5        6        7        8   oct 2    item3        9       10       11       12  sept 3    item1       13       14       15       16   oct 4    item2       17       18       19       20  sept 5    item3       21       22       23       24   oct  in [2]: df1 = df.pivot(index='itemname',columns='month',values='metric1')    ...:     ...: df1 out[2]:  month     oct  sept itemname            item1      13     1 item2       5    17 item3      21     9  in [3]: sns.heatmap(df1, annot=true) out[3]: <matplotlib.axes._subplots.axessubplot @ 0x2a3836cc2b0>

resulting image

so far, good. attempt output chart bokeh, using example base:

in [4]: bokeh import mpl    ...: bokeh.plotting import output_file, show  in [5]: output_file("seaborn_heatmap.html", title="seaborn heatmap example")  in [6]: show(mpl.to_bokeh()) warning:c:\users\<username>\anaconda3\lib\site-packages\bokeh\core\validation\check.py:w-1001 (no_data_renderers): plot has no data renderers: plot, viewmodel:plot, ref _id: b78fd176-bffd-4fd0-9b7c-a169d299f541

this results in empty chart. have done wrong?

p.s. reason using bokeh want switch between different sources of values heatmap on fly using dropdown or similar. however, i'm not invested in of libraries used, if can suggest free alternative interactive heatmaps more easily, gladly it.
