plot hierarchical index?

Community Support
1

I have attached a jupyter notebook showing the example - but is it possible to plot a hierarchical axis similar to the link I have attached in the notebook? Currently what I have done is pop the index out and make it into columns in the dataframe.

plot_question_axis.ipynb (103 KB)

I suppose I have a few questions here:

As written before, can one make a multi-level index look like:

http://news.infragistics.com/cfs-filesystemfile.ashx/__key/CommunityServer.Discussions.Components.Files/265/4718.Capture.PNG

In the example I attached in the previous example, I tried:

p_base = Bar(final_output, values=‘nps’, label=[‘work_location’, ‘month’])

show(p_base)

But the “values” argument has only some fixed values.

when using pandas I can aggregate by using a customer agg function such as:

df_base.groupby([‘work_location’, ‘month’]).agg({‘nps’: nps})

(as seen in the example.)

Is it possible to pass a custom aggregation function. I have tried several ways and don’t seem to be able to.

I was just trying to Directly plot with Bar without having to first do this:

df_base.groupby([‘work_location’, ‘month’]).agg({‘nps’: nps})

then .reset_index() to pull the index out into columns.

Apologies in advance if I’ve misunderstood somthing.

I don’t believe th at
the pre-baked charts support multi-level labels ,
although that is something
you can achieve with bokeh a little more manually:

                    I think that would be a

nice feature, al though it does sound
like a tricky one. Maybe you can add a
feature request on github?

Yes, a pre-requisite to doing this "for real" is to rework the "categorical coordinates" notion, and to properly support nested or hierarchical coordinate systems. I thought there was already an issue for this, but I can't find one, so I'd agree that a feature request is appropriate. This will be a fairly large chunk of new work, which probably won't be able to happen until later this year. For the time being I'm afraid the "manual twin-axis approach" is your best bet.

Thanks,

Bryan
