Hi Arun
You cannot plot a single chart with different sequence of products. If you want to plot both years' data in the order of their ranks, then you will need two charts.
If you need to plot on the same chart, if you have to choose one of the years by which the data will be sorted.
You can toggle the chart with a scorecard with 2 years as two columns, so that users can sort on either of the columns. In the scorecard you can also add a column for the ranks - so for a particular product they know the ranks for 2years.
Hope this helps.
