Plotting (x,y) data points

[webmasterpdx]

I know how to plot a set of y data without x using the statistics_1Var app, but I have 2 columns of data for x and y and I want to plot the data using lines joining the points in the form (x,y).
I can use Statistics_2Var but it seems to only allow a scatter plot (doesn't allow lines joining the points).
I'm plotting a frequency response and need to be able to check individual frequencies using trace.
This is something I'm going to need to know how to do anyhow.
I've searched all the manuals and searched this forum and google, but can't seem to find a way to do this apart from writing a fundamental graphics application to do this.
Any suggestions?
Thanks in advance
