Clustered Bar chart size

Hi

a newbie here to powerBi. i am constructing a bar chart but, the actual bars seem really small compared to the size of the visual. is there anyway i can make this bigger? i have tried to search for "stroke width" which, i've seen in a similar thread (albeit for a different graph) but, i cannot find it.

 

 

Also, query number 2) - my card below

 

is there a way i can get rid of the word "count"
