That's what i wound up doing -- i am totally new to R, so i wasn't sure if there were an easy way of getting the min and max values of a data frame, but i tried that and it worked out well. Thanks.

You can check the range of all items to plot and take the minimum and maximum value across all items. Then draw the plot with the axis range explicitely set to 'minimum'-'maximum'!

That is assuming you know the items you are drawing before hand.
