How to create a XR-Chart?

[#1]

Hello everybody,

I'm trying to create a XR-chart in QlikView but I have not been very succesfull so far.

Anyone who tried this before or has any idea how to do this?

A example of XR chart is: measureing the outside diameter of a piece 3 times and plotting this average on a chart.

So far this is easy with qlikview offcourse.

But we do this piece after piece. And between the averages I want to see the range.

Meaning that I want to plot the difference between the average diameter of part 1 and part 2. (this is one new value again.)

And then the next is the difference between the average of part 2 and part 3... and so on.

Thus creating some chart like the one below:
