load workspace

Hi,
When i load my workspace, i visualize my object with 
the ls()function.

You list the available objects in your Workspace, I guess?
I don't know of the feature to visualize objects with ls().

 First problem is that the saved graph is open like a 
list instead of an image!What is wrong?

What is a "saved graph"? Please be more specific! In addition, this has 
nothing to do with loading a workspace.

I guess you mean a recorded plot via recordPlot(), right? This is indeed 
represented as a list, as well as a lot other objects. But you can 
simply use replayPlot() to plot it into an active device.
Or do you mean a graph describing a graphical model? Or ..... ?

Second problem is about scatterplot graph: how can i 
identify a specific point?

See ?identify

Thanks.
Michele.
