I have a table.
BH XM CJ
A

C

B

The values in the CJ field are not fixed types (in 4-13 cases), but the values of the same types are always the same.
As shown in figure 4 above
How do I create pie charts and pie charts, and print and save the generated charts?

Which of the following statements do you mean the number of columns in a field is not fixed or the data result is not fixed? Just use group by for data. dynamic SQL statements are not fixed.

Is the data result under CJ !!
There may be only one (just forgot ),
I want to generate pie and pie charts !!

Can someone give me an example of creating a pie chart or a pie chart?
