crosslines on graph

hello everybody,

I have a very simple graph. X and Y axes give me a result in the form of a dot. Now I would like to see also the cross lines and, if possible, I would like to be able to decide how long they should be (as the graph will contain 3 dots, very close to each others, I don't want it to be too messy).

Is it possible?

Thank you all

Or you could use another series plotted as xy-scatter line.

Error bars is what I was looking for.

Thank you very much for your help
