TimeSeries plots with Bokeh

问题

NOTE FROM BOKEH MAINTAINER: The bokeh.charts API including TimeSeries was deprecated and removed a long time ago. This question is not relevant as-is to any recent or future versions of Bokeh. To plot time series, use the stable and supported bokeh.plotting API. Some examples can be found here.

I am trying to plot a Timeseries plot with categories.

xaxis_values: startTIme yaxis_values: count

groupby: day

Every day has 24 hours data sets and like this the entire dataset has more than 100 days I am trying to have few type of plots.

Group by day and sum all the counts of every hours from startTime which will give 7 time series plots in one graph.
Separate by day i.e. every mon, tue, wed and so on whatever the number of days n and plot a 24 hrs time series.
Group by hours irrespective of days. i.e. 00:00:00, 01:00:00 and so on

What is the best way to get the better visualization with bokeh or seaborn .
