Display all values for x axis of hours

I have a graph, which shows data of hours on x axis, i'm also using a slicer to display data of spesific group. However 

its not showing the wwhole hours (my data is displaying hours till 10) 

Is there any way to display the whole hours even if there is no data? 

i tried to check show item with no data and put  z-axix to categorical 

I'm not using any measures here, its just counting no of values per hour 

Also, i can not upload any data as i'm a new joiner
