Help with sumproduct equivalent for scatter

[#1]

Hello all,

I'm looking to replicate an excel scatter chart in Qlik which uses the SUMPRODUCT function to plot individual point plots for each axis:

=SUMPRODUCT(--(A2:$A$16=A2))

=SUMPRODUCT(--(A3:$A$16=A3))

... and so on..

This gives a scatter like this:

Can anyone think of a nifty formula in a QV chart which I could use to replicate this?

Many thanks for your help!
