I am working on a project with 300 products we are monitoring, with dates
posted for each stage of completion. I was asked to create a burn-down chart
x-axis being weeks/dates and y-axis being the number of products that have
not achieved that stage in the project. Each stage would have its own
'line'. So in the beginning all products will not have achieved any stage,
so the left side of the chart will have points at the top of the y-axis. And
by the end of the project they will all have points at the bottom of the
y-axis. I have an excel spreadsheet of all the products in rows, and the
stages in columns, with the dates that the product achieves that stage in the
cells. I have never heard of a burn-down chart. Can anyone give me hints on
how to do this?
