Multiple graph selection and editing

[veracity]

Hi,
I have an XY scatter diagram with 25 graphs.
One serie of X, and 25 series of Y.
The points of one series are linked by curved lines.
There are 25 series, 25 curves.
I want to edit the color of the curves in one step.
How to select all curves and set the color of them to black?
Or:
How to select all curves and set the thickness of them to the same thickness in one step?
The problem is the multiple selection of the curves.
SHIFT+ click the next curve does not work.
Any idea?
Thanks.
