Plotting a pie chart on tableau

Question

I am new to Tableau and I am trying to create a pie chart on tableau using the following sample data. Could some one help me out.

I have added Sum and date to the measures side and t1 , t2 to the dimensions side. But I end not getting any pie chart as expected.I wanted to just visualize how the sum of 100 can be shown as percentages of t1 and t2 on the pie chart

Answer 1

Actually it is pretty simple. you will have to rearrange your data as below.

Date        Section      Count

1/1/2012        t1         50
1/1/2012        t2         50
2/1/2012        t1         45
2/1/2012        t2         55

and then refer to the instructions.
