I think by default it will plot a line for each column in the table. It will use the cell value as the Y value, and the row index as the X value. To change the behavior, you have to change two representation properties:
rep.UseIndexForXAxis = 0 rep.XArrayName = 'foo' This will plot all all the columns, except use the "foo" column as the X values. That means the line for the "foo" column is still displayed, and it will be a diagonal line. I just looked, and Paraview has one cheat hard coded- if there is a column named "Time" or "arc_length" then it will be used automatically for the X axis.
