VB.Net Charting - New type of stacked column Chart

See more:

VB

I want to draw a 'stacked column chart' in VB.Net in which a series data is just stacked one above the other in the same column.

Let me explain: Suppose I have three series of data each having 5 values like this:

Series 1: (a1,b1,c1,d1,e1)
Series 2: (a2,b2,c2,d2,e2)
Series 3: (a3,b3,c3,d3,e3)

At present if you draw the stacked column chart it will draw each column with in the following way:

Stacked column 1: a1,a2,a3
Stacked column 2: b1,b2,b3
Stacked column 3: c1,c2,c3
Stacked column 4: d1,d2,d3
Stacked column 5: e1,e2,e3

But what I want is to have just three stacked columns like this:

Stacked column 1: (a1,b1,c1,d1,e1)
Stacked column 2: (a2,b2,c2,d2,e2)
Stacked column 3: (a3,b3,c3,d3,e3)

That is each series point should be plotted one above the previous one.

This seems to be a simple chart - but IMHO it is not possible right now with the chart facility.

This is not a 'Grouped Stacked Column Chart' which just stacks one series value above the other and produces the columns.

I need to make this chart quite urgently.
Kindly help.
