Pie Chart Subplots almost working as i want them but

OK, I have worked out two of the three so far:

2. I would like a physical number instead of percentages on the subplot?

Answer. fig.update_traces (textinfo=“label+value’”) but I have decided to keep percentages so it is actually

fig.update_traces (textinfo=“label+value+percent”)

3. How do I not chart items that have zero value?
This was a bit trickier to track down but I found the answer here - Hiding % labels in px.pie chart python - #2 by nirvikalpa

I added the following to my fig.update_layout;

              uniformtext_minsize=12,
              uniformtext_mode='hide'

and I had to add

                textposition='inside'

to my fig.update_traces entry

Onwards and upwards. Now to find out how to get number 1 dealt with and work out why my legend is showing the position in the dataframe and not the label
