Hi Istvan,

PlotJoined and PlotStyle are options for ListPlot[], not Graphics[].

You cannot get the values of these options if you only have the end 
result, but not the original command that generated the graphics.  (But 
you can take a look at the structure of the graphics object, and see if 
it is made of points or lines (PlotJoined), what kind of directives are 
present (PlotStyle), etc.)
