How to hide empty values in donuts chart

Hi team,

I am generating donut chart for attribute and data like below:

Attribute    Data

1               

2                value 2

1               value 1

1               value1.1

2               value 2

2              value 2

In my donut chart values part is : count of Data and in filter i am selecting attribute = 1 . I will get 3 areas where it will have 1 for blank, 1 for value 1 and 1 for value 1.1 .

How can i ignore blank values in my chart?
