newbie simple graphing problems

this is for a sound waveform graph.
I'm a plodder. having all sorts of trouble with the programming
portion, so decided to try the user interfaces for graphing a simple
file.
data is in a .lvm file, one or two channels, up to 50,000 samples per
file, no sweat. the sampling interval is listed in the header,
simple. Import the data into Excel, strip out the header file, the
extra columns, save as a tab-delimited file. Import into matlab via
data wizard, saves find. Plots as sampled value vs saple number.
Can't seem to change the axis to time via the axis editor. Try adding
a column in Excel with time value, won't read/record the data in the
time vector correctly. GRRR..... How can I get a time value to plot
this stuff?

thanks,
no hair left.
