label width

I haven’t figured out how to get my labels to fully print out. I’ve explored the altair documentation, the vega documentation, and the d3 documentation

https://github.com/d3/d3-format/blob/master/README.md#format says: “If not specified, then the width will be determined by the content.” So I guess my content is ellipsed? But the grantor dataframe definitely has every grant program name fully spelled-out.

grantor = pd.DataFrame(df['Name'].value_counts())
grantor.reset_index(inplace=True)
Chart(grantor).mark_bar().encode(y=Y('index', sort=SortField(field='Name', order='ascending'),
        axis=Axis(title='Grant Program')), x='Name')

BTW, the oddball “Name” in the X axis is because I converted a series into value_counts which retained the “Name” name for the count column name.

I wasn’t able to find labelMaxLength as a possible option. However, .configure_axis(labelLimit=1000) seemed to work. Not sure what the recommended method is.

I’m returning to this same chart four years later (a surprise when I was Googling for answers to come upon my own original question). I figured out a few updates, wanting to update the x label, and keep the wider Y-axis label.

I replaced this code:

Chart(grantor).mark_bar() \
.encode(y=Y('index:N', sort=SortField(field='Name', order='ascending'),
        axis=Axis(title='Grant Program')), x='Name:Q') \
.configure_axis(tickLabelFontSize=12, labelMaxLength=300)

With this, for the win:

Chart(grantor).mark_bar() \
.encode(y=Y('index:N', sort=SortField(field='Name', order='descending'),
        axis=Axis(title='Grant Program')), x=X('Name:Q', title='Number of Grants')) \
.configure_axis(labelLimit=400)

(Not sure why I had to change the order to descending, but it worked.)

UPDATE: Oh, but now the ‘Grant Program’ Y axes label is sitting on top of the grant program names. Back to the drawing board.
