I think the problem I am trying to resolve could be common to all of us.

The default size of a datapoint appearance (such as SymbolSolidBox! for
example) can not be reduced.

Since I can have a lot of series to display all together in one graph, I'd
like to reduce the size of each datapoint to 1 dot.

In the documentation, there is nothing about it (GrAxis etc ...)

Can anybody help me ?
