Hello,
I have trouble plotting a dataset of 2048000 reals. I tried the
following code (as recently suggested on the list):
xdata1 = ReadList[prefix <> "1.dat", Real, RecordLists -> False];
xdata1 = Developer`ToPackedArray[xdata1];
Dimensions[xdata1]
(* yields {2048000} *)
ListPlot[xdata1, PerformanceGoal -> "Speed"]
but I'm simply running out of main memory (2 GB available). Since I
can plot the same data within seconds using IDL, I guess Mathematica
should be able to do the same. But how?
Best,
-Nikolaus
