# Homework Help: Plotting Data in Mathematica

I am importing data as a .dat file into Mathematica and making a list plot. I need to know: a)How to sort the words out of my data? I used to use AllNumeric but that went away with version 6
b)How to switch the axis on my graph? My data is coming in as a pair sequence {1#,2#} but I need it to be {2#,1#} Or I need to know how to rotate my plotting sequence so it will flip.

This is the code I am using

data=Import["Test2.dat","Data"];
b=Drop[data,5]; %This just removes the header from my data file
ListPlot

Try this:
Code (Text):
data=Import["Test2.dat","Data"];
b=Reverse[Drop[data,5],2];
ListPlot[b]

Does you know how to sort words out of data? I have lists of data combined into one sheet and need to remove the column headings out of the data before it is plotted.

Can you post an example in more detail?

It has two columns of that are combined lists of test data. Every so often there will be titles and headings inserted into the two columns and I need to delete these in order to use the ListPlot command.

Unfortunately I cannot upload it in a large section so there is just the start of it attached.

Thank you for all of your help
