I'm sorry, I misunderstood your original post; I thought AspectRatio was working with ListLinePlot, but not with Plot. If it doesn't work with either of them, then yes, maybe it's just something Wolfram|Alpha doesn't understand yet.

Actually I do use the Pro version, and the issue isn't with the ListLinePlot. It's with the aspectRatio.

Thanks Bianca, It really doesn't get much simpler than what i'm attempting. Hence me not uploading the table of values or using the code button (that and i'm typing on my phone and I can't see the code button) Correct- its a list of x,y points. There 50 pairs. X ranges from 0 to 100 and y ranges from 0 to 400. Plotted, the values outline the cross section of a torus (where it becomes two unconnected circles). But what i'm getting, because of the aspect issue is two elipses, long in the Y direction. I thought I'd start with this data set so I cpuld spot any problems. I'm using WAlpha so it's really just the input declaration for the uploaded table of values and then the LineListPlot to get a visual of the values plotted. Plot does work, I think because Alpha doesn't know what else to do with the data (it even connects the dots without the LineListPlot function!) I will try a symetric data set in the morning and see what that gets me. I just wanted to check that I using aspect correctly. It's happy enough with the syntax but it just doesn't seem to affect the plot.
