| In this example, we've shown a "Product Sale Estimation Chart". We're comparing the sale of three products - Inkjet Printers, Laser Printers and cartridges for the year 2005-2009. The data for 2005 & 2006 represents actual sales for the period and hence cannot be adjusted. However, the data for 2007, 2008 & 2009 can be dragged and adjusted. As such, they've been plotted using dashed lines. |
