Annual Bar Chart

[unotiti]

hi, i'm from indonesia, sorry my english is not good

Now, I'm doing task about annual chart in a bar graph

I will tell about my task  first

1. Raw data (format .csv) will be uploaded in system , then display table containing this data

     -No

    -Name

    - Gender (M or F)

 

2.Then the table will appear in system like this:

   -No

    -Year

    - Total of Male

   -Total of Female

 

3. Chart will be changed every year when we upload Data

=> My Question is
  How can I count this gender in chart and display in chart because the format csv  does not exist about year?

 

====Thanks======
