I'm understanding that you need to create a bar chart representing the sum of margin per win, where Win is a dimension and Margin is a measure.
To reach that I first drag Win to Dimensions, the I drag margin to Columns shelf and Win to Rows shelf. You will see that an horizontal bar will show margin level (as a sum or margin) by Win, where win has only two values 0 and 1.
Now, as you are interested in add the number of items (number of records in your data source) per Win, I just drag the special measure Number of Records to label on Marks card. As a result the number of lost (0s) and win (1s) are display on every bar.
I also added the dimension Win to Color shelf in Marks card
Take a look a the attached workbook created with your sample data set to see if it solves the requirement you've described.
I hope this helps

Thanks for the help. It was that last step of adding Win again to the color shelf that I needed.
