stem & leaf single digits***help

#1
I am being asked to create a stem and leaf plot for a series of numbers that are almost all single digits. The plot is to be in 1 point intervals. For example the numbers would be 1,2, 3,3,3,4,5,6,7,7,8,9,10. We had been using symbols for the intervals, but only done 5 point intervals before. Here is what I have now:
0! | 1
0#| 2
0$| 333
0^| 4
0* | 5
0( | 6
0) | 77
0? |8
0<|9
1!| 0

Would this be correct or is there another method recommended.
