My contour map data is a small current (pA). I want to extract contour lines to superimpose on another plot.
You can hit 'extract to contour lines' and you get a bunch of x,y column pairs, but because the Z value is so small the chosen formatting used on the z-axis header label gives 0.00000 for all of the columns.

I just checked and if I normalise the data to pA (*1e-12) the z-axis comes out properly.
I guess this is the result of a string formatting routine that assumes that the data is close to ~1.

Actually, I was wondering if there was some way of adding all of the X/Y pairs quickly to a plot without having to select them individually and hit 'add'. They have incrementally designated (X1,Y1) (X2,Y2) status, so if I select the whole workbook I can hit 'line' plot and they all get plotted in a new plot, but adding them to an existing axis is a bit trickier (I guess can make a new plot as above and add the contours to that).
