Creating a bar plot from a categorical subarray

Dear all, i am trying to plot my measured data against a categorical array. In my script i used 'sample1' as a categorical array that contains a portion of 'samples', which contains all sample names.
(The same goes for 'rq1' which contains the corresponding values to the measured samples extracted from 'rq')
I extract sample1 out of samples via
sample1 = categorical(samples(7:10))
which correctly produces this output:
sample1 = 1×3 categorical array
Ctrl male Ctrl female 13_0551
when I bar plot the 'sample1' values against 'rq1', it produces an output that contains all the content from 'samples' on the x-axis, and not just 'sample1'
bar(sample1, rq1)
however, manually creating a categorical array 'test' that contains the same items using
test = categorical({'Ctrl male' 'Ctrl female' '13_0551'})
and plotting against 'rq1 results in (almost) the desired output, but obviously I dont want to write down every item out of the original list with 72 items.
bar(test, rq1)
is there a way to work around this problem?
full code is:
sample1 = categorical(samples(7:10))
rq1 = rq(7:10)
test = categorical({'Ctrl male' 'Ctrl female' '13_0551'})
bar(sample1, rq1)
%bar(test, rq1)

idx = 7:10;
bar(categorical(samples(idx)), rq(idx))
If you want to eliminate categories with a bar height of 0,
idx = rq~=0;
