How to plot smooth curve with three variable

Dear sir/madam

I have an data set attached with the query, the first column is distance, the second is depth, the others are stations with conductivity values.

I want plot having X-axis as distance, Y-axis as depth with varying conductivity values for different-different stations.

What do you mean?

I want plot having X-axis as distance, Y-axis as depth with varying conductivity values for different-different stations.

Do you want to have a 3D-plot (see "plot3" or "surf" and similars)? Or do you want to have a set of 2D-plots in one axes object (see "plot" and "hold")?
