Re: Questions on MultipleListPlot: One answered, one still troubling

I previously asked about two problems I am having with MultipleListPlot.


Regarding my first question, I received several responses which directed
me to the use of sequence to flatten a list of lists for the argument.
Thanks for the help -- the technique is used in the example below.

Regarding my second question, relating to the tendency of
MultipleListPlot, when contrained by a PlotRange argument, to go ahead
and plot data points over the plot label, several asked for an example,
which I provide below. If you execute these cells several times, you
will not have to wait long to see data points -- but not the joining
lines -- plot right over the plot label, even though they are out of
range.

Any ideas?


data = Table[{n,Random[]},{4},{n,10}];

MultipleListPlot[Sequence@@data, PlotJoined->True]

MultipleListPlot[Sequence@@data, PlotJoined->True, PlotRange -> {.2,.7},
PlotLabel-> "Test Label\nLabel Line 2\nLabel Line 3"]
