Plot a struct field that is an array of doubles

I have data stored in a struct with fields 'BO' and 'tota' which I want to plot something like:

plot([data.BO], [data.tota])

but the problem is that each element of the 'tota' field is an array. I want to plot all of the array as multiple y values for the single x value. Example data structure and plot below (plotting was accomplished by breaking the single struct into multiple standalone matrix).

In truth, I want to do something like:

figure; hold on;
plot([data.BO],[data.tota(:,1:end-2)],'o')     
plot([data.BO],[data.tota(:,end-1)])           
plot([data.BO],[data.tota(:,end)])

The best I can do is

b = cell2mat({data.tota}');
plot([data.BO],b(:,1:end-2),'o') 
...

But I was wondering if there is a more elegant way to plot directly from the struct without needing to duplicate data into a bunch of temporary variables.

plot([data.BO], vertcat(data.tota),'o')

Thanks!, that should have been obvious. There is no way (without saving off to a new variable) to easily index in and limit the plotting to only a subset of the columns?

No, but you can easily suppress certain lines after the fact, e.g.,

data=rand(10,4);

H=plot(data,'-o');

[H(1:2).Visible]=deal('off'); %suppress first 2 lines
