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 -- =C2=BBIt is not worth an intelligent man's time to be in the majority. By definition, there are already enough people to do that.=C2=AB -J.H.
