Question about pie chart
I have a question about the pie chart.
I would like to make a summary pie chart of my data.
For example, a statistic data only contains the user name and their income.
So, the data are as listed below:
If it only contains this four data, how can I build a pie chart that only contains those three user and their total income?
The results should be A: 40%, B: 10%, and C: 50%.
I used the User and income to build my pie chart, and the results are A: 30%, B: 10%, C: 50%, and A: 10%....
What functions should I use?
Is their any one can help me?
Thanks very much.
