Series overlap
When analyzing sales, we will often come across data series that would be convenient to display using a Stacked Column or Stacked Bar chart, but due to their nature this is not a good solution. For example, if we have a production cost and a sales price, we need to calculate the price difference in order to show the production price and the price difference as two complementary series on the chart; their sum is, it is easy to see, the sales price. Can we create such chart without additional calculation?
