Create a for loop with a property node linked to the XY graph. In the loop feed the active plot property with the indexes of the different plots you want to set the properties of and then wire up the rest of the plot properties...
If you want *all* the plots identical just wire the loop index to the active plot property and set the loop to run as many times as there are plots. As shown on the attached picture (making plots 0,1,2,3 & 4 identical in line style and color).
