Pie chart

Hi everyone,

I have to plot in a graph, maybe a pie chart, some alphabetic values. I have a table like this:

Name      |      Q.1    |       Q.2    |      Q3     |

Jenny      |      N/A    |        C        |       AK     |

Rob         |      C        |        C        |      N/A    |

As possible value I have only: N/A, C, AK, NC, PC.

I would like to have a graph in which through a slicer on the name it will show the percentage of the answers. For example, selecting rob I would like to have a pie chart which shows 66% the value C and the 33% value N/A.

Thank you very much.
