like double pie charts it possible in xls sheet but same thing I would like to see in qlik sense like how much product share in area it show in inner pie chart and how much we get the return from that area which is outer pie charts.
The nearest approach within qv (and without extensions) would be to overlap two pie-charts and adjust the visibility and color from various properties like title, border, legend and so on. But it would be not very flexible or look very beautiful.
Pie-charts with more than 5 - 6 values have a bad readability for users and with such a second level even more. It creates rather confusion than any added value. I suggest you looked for another kind of (inbuilt) visualization. Maybe a combination from various charts(-types) which form a logical line or a grid.
Perhaps this link can guide you to finding a suitable chart type? Introducing Qlik instead of Excel sometimes require that you challenge your habits and the ways you consume data. Why not do a could of different charts to present the same data and ask your end-users which they think is best?
